Was wondering whether anyone knows if the use of the encryption function on the P7100 will result in any noticeable loss of performance on the device...Does the encryption of the file system result in a greater use of processing power...?
Thank you..

I know this is a noob question but please enlighten me. Because I'm so confused on how to perfectly run jays buttery goodness. I'm using SmoothRom 4.2.1 and M-Kernel @1.4ghz on a performance governor. Thanks! Any recommendation is totally appreciated.

It really matters on which you want more... performance at the expense of possible data corruption, or data integrity at the expense of some performance.

If you get a database corruption, what is the likelihood that you can recover from that if you have a nandroid or adb image?
Also, what if you do that apps2sd mod, do you still need to disable fsync?
Does turning off fsync make a noticeable real-world performance difference? I know it brings faster app installs and such, but does it also make a difference in everyday usage?

Kind of risky... checkout this thread...

Rgrds,
Ged.
I am aware of the risk, thanks. So I am wondering if the risk is worth the potential benefit.

After flashing I always Fsync off (understanding the risk).
I don't do this for a higher Quad score but to have somewhat faster web loading.
(just my 10 Yens worth - ymmv)

Well... I've just tested... disabled Fsync using TricksterMod... and 'Set On Boot'.
Upon reboot, I noticed a very marginal speed benefit... but not enough in my opinion to justify the risk.

There are no objective answers here... you'll have to try it for yourself, I'm afraid.
Good luck.
Rgrds,

Well, I have tested of course too, but not sure if the speed gains I have observed are real or placebo. Does anybody know if disabling sync requires reboot?
Sent from my Nexus 7 using xda app-developers app
Do not need to reboot. Just try it, for me it made the horrible io lag the nexus 7 has less noticeable when doing heavy io like downloading apps or flipboard, things like that.
I went from stock kernel to Franco and didn't see a huge improvement until I disabled fsync. Now my experience is much nicer. Faster wake from sleep, less io lag, overall less lag.

Give it a try and find out. (If you are one of those folks that OC's and isn't concerned about kernel crashes, make a backup before you begin)
The writes have to happen eventually. (Hopefully before a kernel crash or freeze!)
The point is that it's not something that gives you something for free - it merely moves sluggishness from one point in time to another. I suppose it also means that it (transiently) uses more RAM for caching of dirty pages that have pending writes.
good luck
Hi All,
Want to share with you, experimented the XXLT5 on GTN7000. Superb ROM....so far no issues....you name it, it works fine. Note the downloaded file is above 1GB...seems this has all the fixes required. You can root it as well....if any issues found on this stock rom do let me know....will be interested to catch the bug.
Link for download...http://www.hotfile.com/dl/213299077/83496c8/N7000XXLT5_N7000OXXLT2_XEH.zip.html
Link for root : http://d-h.st/GiO
Installation...as usual....Odin...so have a latest pack..open, select the PDA and good to go.
the hotspot works?

Yes...works fine.
I'm running N7000XXLT4 as my build -- is this simply an improved update that just hasn't hit my German unit yet?
And what's better in this LT5 from LT5 posted on may 7th? http://forum.xda-developers.com/showthread.php?t=2267748 Why we need another thread?

I upgraded ota from Gb to Ics. And i do a factory reset before. Then on ics i didnd factory due to brick bug. And ota update to JB UAE version. My cpu is always 15-35 % on idle and above 60% with any applictation like Google+ or Hangout..
I did wipe cache and factory reset in recovery.
Now i flashed LT5 And wipe and factory before and after. But still the same?

Do you have a cracked screen? My CPU idled quite high when my screen was cracked.... Did you also experience the above problems with CyanogenMod?
Screen not cracked, outer body have some cracks. Phone is running smooth in gb and Ics

Something must be wrong with the phone if you have such a high CPU usage after a fresh install. Send it in for servicing.

first, whats your upgrade procedure, try without restoring stuff and let os settle in. restoring app+data usually causes this with me.
Also what app do you use for measuring cpu usage. That may be off for some reason. Also note cpu utilization v. s. governor. Example on demand scales up frequency when e. g. uses 80%, so it will seem high, but in regard to frequency it is not. Due to battery savings lower frequencies are used, until 80% frequency is reached before going to a higher frequency, thus for same task higher utilization of that frequency it may not be a bad indication is what I am saying.
Now a rom usually needs some time to synch, perform breakin tasks, scan all media etc, try to see through settings, development options then cpu utilization what is utilizing cpu. Maybe app has gone bad, rogue, or maybe its expected.
M using CPU Z, thanx for utilization info

your welcome, you can check also cooltool, that has a nice overlay you can position anywhere. You can configure and show e.g. frequency, cpu utilization, temp(battery I think), pretty fun.

Okay so I am aware that it is a method to get rid of lag, but it is also a safety feature to prevent the phone from overheating. Does anybody have experience with disabling it?

First try to find out what is PVS binning of your G2. I have 3 and when I tried to disable thermal throttling my G2 couldn't boot, rebooted before sim pin input and stuck in bootloop. I could only enable throttling back when freezed thing in freeger. So, YMMV of course, just be warned

Mine is PVS 2 - any ideas?
Mine is Bin 4.. No issues at all disabling thermal throttling.. Supposedly Thu higher your bin number is, the better your chip is..
Sent from my LG-D802 using xda app-developers app
Yes since it needs less voltage to achieve same clock speed as opposed to lower bins.

I remember back when I had a Galaxy Nexus that it was possible to not only overclock it's CPU and GPU but also its memory. Now this got me thinking that since the Nexus 10 has a less than ideal amount of memory due to it's high screen resolution, maybe overclocking its memory might help performance and multitasking.
Now the question is.... is this possible to do?
If I can remember correctly some of the custom kernels have memory controls. KTmanta comes to mind. I think you may need the kernels control app to get at those settings. Also I'm using Tempest ROM an OMNI ROM variant and it includes numerous memory settings which may be what you are looking for.
You would need to enable developer mode then Settings->Performance, settings select "tabbed mode" then select the "memory" tab.
I've never messed with those settings myself but they are there for your amusement.

Maybe try this
http://forum.xda-developers.com/showthread.php?t=1719934
But of course depends on what kernel you are running, haven't used it on my n10 but works amazing on most my other devices
Sent from my Nexus 7 using XDA Premium 4 mobile app
KT has memory frequency exposed and I think that is the only one. That being said, no matter what settings I try on KT, Trinity 10 outbenchmarks it with mostly stock settings. That suggests to me you should probably look for a different way to improve your RAM performance, i.e. minfree values.
