Some brief explanation for the contents of the script
1. /proc/sys/vm/laptop_mode
How many seconds after a read should a writeout of changed files start (this is based on the assumption that a read will cause an otherwise spun down disk to spin up again).
2. /proc/sys/vm/dirty_writeba​ck_centisecs
How often the kernel should check if there is "dirty" (changed) data to write out to disk (in centiseconds).
3./proc/sys/vm/dirty_expir​e_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is in general a good idea to set this to the same value as dirty_writeback_centisecs above.
4./proc/sys/vm/dirty_ratio​
The maximum amount of memory (in percent) to be used to store dirty data before the process that generates the data will be forced to write it out. Setting this to a high value should not be a problem as writeouts will also occur if the system is low on memory.
5./proc/sys/vm/dirty_backg​round_ratio
The lower amount of memory (in percent) where a writeout of dirty data to disk is allowed to stop. This should be quite a bit lower than the above dirty_ratio to allow the kernel to write out chunks of dirty data in one go.

I thought I should return the Tweak Manager's 00tweaks script back to initramfs

let me give it a try

what if i already have 00tweaks? should i had this script to the current file or substitute?

Hey, the values are similar to CF-Root Great then, gonna try it out

What should I do if I want to try your script, but I have already used CF-Root With Tweak Manager that also using another script in 00tweaks file

Wow I just ran this on GSB 3.8 workshed for the eris. And WOW the phone rings on 1 1/2 rings with a ringtone and the screen lights up. Very nice work. I hope you don't mind but i posted a link from the eris fourms to this file. I been looking for for so long on how to get rid of the rintone LAG and WOW i think you got it! Thank you

How to create the script?
Thnx

A lil question, this wont collide with the V6 Supercharger?

Hey guys,
can somebody please tell me how to make a script of this? I really want to know, but i'm new to this.
I can't find anything on the "search".
Cheers

I think something does because I am getting complete homescreen redraws since I started using this a couple days ago. The phone seems to boot way faster and seems to run a little better but I think there is a conflict somewhere.

You don't have to make a script just copy it all to a text document on your desktop and after you save it delete the .txt at the end. Then put it on your SD card and use Root Explorer, or similar, to move it the proper location. I set the ownership and permissions the same as other files in the same location and rebooted. Just be sure to tap the "R/W" button at the top of the screen if you are using Root Explorer so you have read/write permission to work in the folder.

Hey,
thnx man. Found notepad++ and made a text file with that.
Tried the script for a couple of ours and for my personal feeling it made my phone slower at multiple points. Also Quadrant standard gave me a lower score (11-13) then when i'm using 00tweaks/v4 tt.
So this goes out the door.
Cheers

I hate bringing things back from the dead, so I apologize in advance.
If I want just the atime section of this script, do I just keep the first part? Where does it stop?

AUTO
what does the auto do in the mounting script?

Build.prop / scripts

Originally by knzo, I have tried many on my phone and thought I should share with my fellow streakers...
On my ROMs adventure I've been collecting some tweaks and scripts and seems to me it's now time to share it. While some values in terms of optimization might fluctuate from device to device, I've found these pretty consistent throughout many.
Build.prop
(edit your /system/build.prop with a file manager with root access)
Careful for already existing settings. In this case, just change the values.

1. strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;

echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. vm management tweaks
Code:
echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;

echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
5. battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot

if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"

GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)
For improving GPS lock time and signal.
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin

b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Other tweaks or guidelines
1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)
Code:
You can use AdFree application for this or changing manually your hosts file.
Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.
Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.
Code:
http://uot.dakra.lt/
4. Use Google's dns servers
Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)
Code:
http://goo-inside.me/superuser/
6. Disable sync feature in sqlite
(author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)
Code:
Patch file here: http://forum.xda-developers.com/showthread.php?t=903507
7. Do not use task killers.
Alright, I think this is it for now.
If you have any other tweaks or better values, you can PM me and I'll include them.

nice awesome tweak values there
i'll try it soon
thanks for the tips my friend

WOW!!! Nice going! keep them coming.

scripts
do these only work on custom roms, or can they be used on stock? i think the files called system.prop or something instead of build.prop, hence why i ask before i start attempring to alter anything ?

Is there any way to stop dell streak to shut down when remove back cover?

Its a kernel hack, unfortunately. DJSteve's Streakdroid and DSC are the only ones I know of that have this.

@smnc you seem to be a Senior Member. With any respect, is it that difficult for you to understand that was nothing about the Streak (I don't even know what you are talking about) but a "generic" android/linux setting?

I'll assume we have a language barrier here and that you weren't being intentionally disrespectful.
1) You posted in a thread that has been dead for 11 years+, for a specific device that has been out of production for just as long. Expecting any response should have been a long-shot, but expecting a non-device-specific response is just odd. The only reason I saw your post was because by sheer dumb luck, I happened to have notifications turned on for this thread from way back then.
2) While read_ahead_kb may be a "generic setting", storage device paths such as /sys/devices/virtual/bdi/179:0/ are not. Different Android/Linux/Unix devices, and even differnt builds for the same device may arrange storage devices in different configurations, so finding out the path for the internal storage on a Dell Streak 5 running Android Gingerbread will likely not apply to whatever device you're working on.
3) The actual read-ahead cache size from a 12-year-old device is not likely to be useful on a modern device as storage technology and speeds have changed dramatically since then.
Perhaps if you posted in a general channel, or one specific to your device, someone might be able to give you more useful information fort whatever your project is.
Hopefully that helps you.

Doubts About DroidXGovernorsV2.2 and other little doubt

First I want to apologize for my strange English (Google translator)
Returning to Questions, I would like to Know how to Remove the vibration when the screen Unlock
I also like to know how to do DroidxGovernos work on my machine because the installation is completed via CMW put the Set CPU does not recognize them, any thoughts?
Brazil to Use Retail 2.3.6 Root, Boot menu, and CMW working
Thanks

Not sure on the lockscreen vibration.
DX govs work by adding in the modules into /system/lib/modules/ and loading them with an init script. So far, they've worked on Bravo, Defy, and Defy+. Did you enable overclocking in the bootmenu? Its necessary. Some users even have to enable "Load All Modules". I've never had to, but some have. I can tell you the Boostedass works wonders on ICS with battery time. Added 16 hours of battery life on Quarx 2012\05\12. Miui runs for 2 days with about 4-5 hours of mp3 playing a day, 1 hour of wifi browsing, and being a bit anal with disabling what I'm not using with the power widget (3g, wifi, gps, etc...)
There is that chance that they just don't work. InteractiveX, from the same rom I found these governors in, won't work at all on my Bravo. I know that on CM7\MIUI\CM9 on the Bravo all that I have to do is flash the zip and enable them in No Frills and they just work.
Boosted, as well as SIO, are now built into the latest bootmenus for the Defy and Bravo now because of how well they work.
The full init script I'm using, and included with DX Gov 2.2.
Code:
#!/system/bin/sh
#Load Modules for IO Scheduler and Governors
insmod /system/lib/modules/cpufreq_smartassv2.ko
insmod /system/lib/modules/cpufreq_BOOSTEDassV2.ko

#Set IO Scheduler, use "sio" "noop" or "cfs" (sio and noop recommended)
for i in /sys/block/mmc*/queue; do
echo "sio" > $i/scheduler
done
#Tweak IO Parameters
for i in /sys/block/*/queue; do
[ -f "$i/rotational" ] && [ "`cat $i/rotational`" -ne "0" ] && echo "0" > $i/rotational
[ -f "$i/read_ahead_kb" ] && echo "2048" > $i/read_ahead_kb

done
#Set SD Card read ahead cache
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb
You can remove the smartassv2 insmod line (script above, 5th line) to save a tiny bit of ram; and the last line is the SD Speed Tweak (also script above, last 2 lines). It can be removed if you use other values or another mod with them included. I only included it so all the read ahead values were the same.
You can also use the following script to load and configure Boosted or SmartassV2. It doesn't work on the Bravo. Some reason echoing boostedass causes my phone to freeze on boot. Perhaps you'll have better luck than me.
Code:
#!/system/bin/sh
#Use either BOOSTEDassV2 or smartassV2. Comment out (# at beginning) all lines if using stock governors.
echo "BOOSTEDassV2" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
#Only use one or the other, and only if you plan on using BOOSTEDassV2 or smartassv2
#Tweak BOOSTEDassV2

[MOD] HBBTweaks v32 (11/23) - battery and performance

HBBTweaks is a package of Kernel and build.prop tweaks I've done (read, tested, benchmarked, saw the sources, etc) and shared on a Facebook group since version 1 (long time ago huh?)
Lots of users tested and most of them noticed improvements in battery life *and* performance, so I decided to publish here as you may find it helpful too..
It is just a .zip file you can install with CWM or TWRP the same way as you install a ROM. It should work on ALL ROMs but *I* have only tested it with CM10.x and CM11 ones. Don't worry, if anything goes wrong you can easily uninstall it and everything will be reverted.
WARNING: it will activate some overclocking (cpu: 1050mhz, gpu: 700mhz) and undervolting *if* your Kernel is able to, so your phone may get unstable if it's not as GOOD as mine, LOL.
If you get some reboots after installing it, try the alternate versions.. First try a1, then try a2. They won't save as MUCH battery as the original one but you'll definitively notice improvements as this isn't just a "switch-on-the-OC script" !!
Download link: http://d-h.st/iuT (Multi-installer, with two "alternate" versions and uninstaller included)
See if your phone gets a bit more responsive and if your battery life is better then post your thoughts here
CHANGELOG
31 -> 32
abyssplug or pegasusqplus as default
faster gpu clock reaction
sqlite3 and zipalign updated
touchboost to 800mhz with 200ms duration (default was 500ms)
higher intervals for the kernel scheduler
won't save any modified data to mmc/sd for up to 5m
tweaked abyssplug and pegasusq
won't disable zram, instead will use it more if it's already enabled
30 -> 31
sqlite3 included to optimize some databases
other minor tweaks
don't forget to reinstall it after any rom update!
29 -> 30
it tries to disable zram giving better performance and battery
ext4 and sioplus tweaks!
abyssplug by default, tweaked also
28 -> 29
kernel's sched_* back to default. better performance
testing some ext4 tweaks
27 -> 28
Aroma installer providing 2 alternate installation options and an uninstaller.
10.1 (and MIUI) compatible
Different swappiness and page-cluster values for zRam swapping or "normal" swapping
ddr_opp set to 100%, don't know if it will stick. it's faster here.
tweaked the way minfree is set and also the mounting options
26 -> 27
A typo (while I was translating) was preventing undervolting.. that's why nobody complained about reboots with the full version.. lol

Works on JB roms too ?

Normally I can't overclock, it causes the known freezes and reboot issues.
So which verison should I pick? Alternate 1 or Alternate 2?

It's not a big overclock to the cpu(it's limited to 1050mhz), it's mostly to the gpu.. so, I think you could try the original one and then a1.. come on, the files are so small..

Haha I know, sorry for my lazyness :cyclops:
Edit: You should/can mention in the OP that OC is limited to 1050mhz.

I will download and try!
I am using Resurection Remix. The rom is awesome but i am having some battery drains..
I will try this tweaks for some days and test if the battery goes better
thanks!

@fbs Thanks man, tried original one and everything is fine. Waiting a couple of days for making a correct review. One question, I set CPU to 1000 (max.) and after that I flashed your script. When looking for which states my processor has been on there is 1000 Mhz the highest (I've set this before flashing script) but is my CPU actually running on 1050mhz? Would like to know more about this script
Thanks anyway, it's nice :thumbup:
PS; On what ROM are you now?
sent with my S Advance.

Well it sets max frequency to 1050 right after booting, but if your ROM or any app (like No-Frills) set it back to 1000, it will keep on 1000.
Right now I'm using Paranoid 4.4 build by t4n017 available here.. it's faster than vanilla cm11 and Vanir, to me..

v26 changelog?

Did you use V25 ?

Is KitKat based custom ROM supported?

Yes, I was on v25.
The system is a little snappier, but the most noticeable change is the battery save (undervolting).
I got 4h and 30m of screen on and my battery is not good. I have it for 18 months.
I'm on PA 4.4.3.

Essential
II'm using this tweak since version 23. Currently use version 26 alt1 with Vanir 4.4.3 ROM and everything is running perfectly. Really feel improvements in battery performance and the performance of the device. :good::good::good::good::good:
Thank U Bro.

and what about the battery life

@fbs
It is not recommended to flash this script right after flashing ROM and Gapps, right?
Booting is a requirement.

You can flash it any time. Don't need to boot after initial ROM/GApps flash.. :good:
It just won't work if you install it BEFORE the ROM itself as the ROM's installer will format /system and everything will be lost

If anyone's interested, here are the two main "scripts" my tweak uses. Anyone could read it inside the .zip or /system/etc/init.d folder, but I know some are lazy then I'll copy/paste here
