I did a factory reset (latest AOSP w/ Motley kernel) and installed nothing but Androbench (didn't even add my Google account) and got these Androbench results:
Squential Read: 24.3 MB/s
Sequential Write: 1.41 MB/s
Random Read: 7.81 MB/s
Random Write 0.23 MB/s
SQLite Insert: 18.92 TPS / 15.85 sec
SQLite Update: 23.45 TPS / 12.79 sec
SQLite Delete: 22.67 TPS / 13.23 sec
Browser: 2830 msec
Market: 891.25 msec
Camera: 1404 msec
Camcorder: 1323.75 msec
Pretty abysmal overall, random write especially falls off the charts altogether. This is really sad since my N7 used to run great but recently has degraded significantly with lots of lag and ANRs.
Is it safe to say I need to RMA this device due to bad storage?
Have you tried using a different ROM? Try one like Paradigm or Paranoid Android and see if there's a difference. When I ran quadrant on some ROMs I got around 2,000 consistently for I/O but when I ran it on some others (eg. Paradigm Android, BAKED Blackbean) I scored 7,000-8,000 consistently (I also used _motley's kernel).

Thanks for the suggestion. I get ~1,200 for I/O in Quadrant normally.
I installed BAMF Paradigm and my scores got much, much worse (about 1/3rd as fast across the board). I tried installing Trinity kernel on top of Paradigm and it's much better (roughly 2x standard). Unfortunately my random write is the same, which is absurdly, brokenly low.
However my Quadrant score is now ~7000... I just don't know what to believe any more :crying:
What I/O scheduler are you using?
how much space do you have left in your storage?
Using the default scheduler in any given case. And I wiped my SD Card so there's plenty of room left.
I just un-rooted and installed the factory image - the I/O performormance has largely jumped back to normal now, so I'm at a complete loss as to what's going on I'm going to take it and run with stock for a while I think.
Thanks so much for the help all!

My Nexus 7 has recently developed incredibly slow write speeds to external memory. I'm certain that they used to be the same as most benchmarks that I've seen for the tablet, but as of a few days ago they've plummeted. Restarts don't do anything for it, and I've killed all running apps to make sure nothing was using IO excessively.
Androbench reports sequential writes are at 0.37MB/s which seem awful. AnandTech's review last month stated 8.43 MB/s for sequential writes under the exact same conditions.
Opening apps now seems a lot slower than usual as well, and I've checked there aren't any rouge CPU spikes to blame. I read on another thread that disabling USB debugging helped up IO speeds, but my problem still exists.
Does anyone have any ideas how to fix this, bar wiping the memory? I'm running unrooted stock, for reference.
Thanks!
Have you installed any new apps lately?

Yeah, but I went through them all and uninstalled them. Didn't seem to make a difference. And for the benchmarks, I make sure there's no apps running in the background, Logcat output and a look at the list on "adb shell top" confirms there's nothing running.
try a data wipe/factory reset and then only load your benchmarking app. See what you get that way..

I'm in the same boat, exactly the same poor storage performance. I did a factory reset (latest AOSP w/ Motley kernel) and installed nothing but Androbench (didn't even add my Google account) and got these Androbench results:

So I ended up flashing (and rooting my Nexus at the same time), and problem seems to have disappeared. Seq writes back up to 10.92 MB/s, looking pretty healthy.
Sorry I couldn't figure out what the problem was, hope you get your issue fixed!

Yeah, I did the same thing and my speeds are back to normal too. Makes me wonder if it's a kernel thing in non-stock kernels
So my quadrant score sucks because my i/o category is way low... it seems that write speeds (especially database writes) are really killing it.
When you guys say you just reflashed, do you mean just using CWM? To a new rom?
Thanks
Hey guys,
I apologize if this has been asked over & over... but I'm a little frustrated here.
Basically I'm seeing absolutely horrible random write results on both of my nexus devices (VZ GNex toro & N10). Bascially the numbers I get don't even show up on the charts (1 or less MB/s on Random Write... around 40 IOPS).
I have done various factory resets, freshly installed my custom ROMs, etc. (I have also run the lagfix trim operation that is under discussion on these boards recently), and have not really seen much difference.
Should I chock these results up to something with my current ROM / kernel that the ROM is using? (I'm running Jelly Belly 12.1 on both devices atm for what its worth).
In general, things have been "ok" performance wise, but I'd really like to know why I'm getting such abysmal I/O performance...
Thanks!
So I have been trying to decide if the micro-stutter I get with my LG G2 V980 is just my hyper sensitivity or if my phone has more than other people's, since many people say it is super smooth. I rooted my phone the other day so that I could side load the tethering app and change the CPU governer from ondemand to interactive using Trickster MOD. I did not benchmark my phone before this, which I should have, but subjectively my does appear faster.
However, I still have some micro-stutter. Not too bad, but there none the less. This got me thinking of TRIM. I know that a new phone that has most of its memory free should not need to be trimmed yet. But for ****s and grins I downloaded lagfix and ran it anyway. It is really too early to tell if it made much difference, but the little I have used my phone since then have been promising.
And this got me thinking - what if some people had trim issues with the phones when they got them? We don't really know what LG has done with some of these phones before we got them, right? I downloaded AndroBench form the play store and ran a microbenchmark. From what I understand, the Random Write speeds are the ones that usually cause a ton of lag/micro stutter in phones. I did not run it before I ran lagfix, but I thought I would post my results now and ask others what they are getting. Especially people that think they have 'stutter' issues. Can you run an AndroBench micro benchmark and post your results?
Mine is attached. Verizon, stock cleanrom, rooted, interactive governor, daily scheduled lagfix.
Edit: Ran the test 2 more times, and got 7 MB/s and then 14 MB/s sequential write.
My results are terrible compared to yours :S but i have no stutter or lag problems, so im a bit confused here.
Btw im on g.lwarnes stock rom v1.06 and his 3.01 beta 2 kernel, also ive used the lagfix and it didnt matter at all.
Cant upload a screenshot so the results are seq read 85k seq write 9.79k random read 12.75 and random write 0.6
Sometimes g2 slow down a bit but nothing to worry about
I'd like to ask G2 users to post Androbench results from different ROM versions.
Thing that I'm interested in is random write performance. Depending on review I checked it varied from 0,6 MB/s to 1,34 MB/s (200 IOPS to 380 IOPS respectively).
I'm considering buying such a device but if random write is really at 0,6 MB/s then it's not good enough for 200% smooth operations in my opinion.

Malladus 1.2.4 VS980: https://dl.dropboxusercontent.com/u/38348368/Screenshot_2014-01-02-05-30-10.png As you can see its 1.37 for me and the reads are extremely high, I don't notice any lag either, of course this rom has trim built into it, but this phone is fast enough already.

I ran this on my Kit Kat on pa_g2-4.0-BETA-20131231: https://dl.dropboxusercontent.com/u/38348368/Screenshot_2014-01-04-21-56-20.png which is way higher than Stock based rom. No idea if its accurate or not, but I know for a fact that Kit Kat runs even better than stock does. :good:
F320 4.4 kitkat stock 350 IOPS rnd wr
I just bought a used Note II GT-N7105 so before I sell my GT-N7000 I decided to take advantage of it not being needed and run a quick comparison between the Samsung Jelly Bean 4.1.2 firmware and the latest CM11 (20150419). In each case it is absolutely stock except for the installation of Quadrant apk. The stock firmware is really stock (no 3rd party recovery) and CM runs with the CWM version it ships with. No accounts set up, no SIM, nothing removed or added except a 16GB microSD containing no media except a signed recovery and a modern kernel (to enable installing cm) and a cm11 nightly zip. The only additional change from set up is to connect to my wifi.
I ran the test several times on each OS and below are the best results from each:
Samsung 4.1.2
Code:
Overall: 4505
CPU: 6730
Mem: 5003
I/O :8669
2D: 321
3D: 1803
CM11
Code:
Overall: 4030
CPU: 7581
Mem: 3265
I/O: 6865
2D: 243
3D: 2196
Although not every run of the benchmark produces identical numbers the same differences between each firmware are reliably apparent in every test - CM11 has much poorer 2D performance but slightly better 3D. CM has better CPU score but worse Mem and slightly worse I/O scores.
CM 10.1.3 benchmark
Same benchmark, same conditions but this time it's CM 10.1.3 which is the last official stable CM release for the GT-N7000. This time I installed Lanchon's FPBug fix kernel so as to avoid bricking the device right before I sell it... http://forum.xda-developers.com/gal...ernel-fpbug-stable-4-x-kernel-galaxy-t2978107
Code:
Overall: 3765
CPU: 7135
Mem: 2324
I/O : 6094
2D: 314
3D: 2147
These were the best results of 5 runs, all were similar.
The most striking thing is that in CM 10.1.3 2D and 3D performance are excellent, comparable to or even marginally better than stock. CPU score is great. I/O not great but not terrible. Memory score ...oh dear - really bad every time, even worse than CM11 and that was poor already.
Probably in real use the most visible difference to us users is that 2D performance is excellent - no lagging, no jerkiness, no stutters - a really snappy feel. KitKat was a giant leap backwards in this respect.
10.1.3 feels nice and usable so my next post will be one more set of benchmarks in 10.1.3 with JB gapps installed, my google account set up and all my usual apps installed, and everything up to date, as far as is possible.
CM 10.1.3 + Gapps benchmark
CM 10.1.3 with Gapps and Rekey patch. https://play.google.com/store/apps/details?id=io.rekey.rekey
Code:
Overall: 3599
CPU: 7161
Mem: 2368
I/O : 6004
2D: 317
3D: 2147
The undisputed best performer is Samsung Touch Wiz JB 4.1.2, and by a very long way.
Lollipop Benchmarks
I noticed Bauner's NightOwl LP 5.1 (unofficial CM 12.1) got an update this week so I installed it and benchmarked it. As above, totally default except Quadrant installed and my wifi connected. No Gapps:
Code:
Overall: 4577
CPU: 11438
Mem: 3206
I/O : 5853
2D: 235
3D: 2152
This is the only ROM, so far, whose overall benchmark score is better than stock Samsung Jelly Bean. The 2D performance and Mem scores are still poor and the CPU score seems remarkably high and I wonder if it is reliable or credible. I will try Antutu next to see if it produces similar remarkable differences.

The cpu scores can be higher, because my higher thermal throttling values.
With the stock values the cpu is running very fast into thermal throttling.
The differences in I/O and memory scores can be come because lollipop is much more complex and there are running much more services in the background.
It would be very interesting to see the results with the raw kernel.
If there the scores for I/O and mem are higher I should check which changes in my kernel are causing the regression
OK the thermal throttling explains a lot.
Last night I ran antutu on JB and on NightOwl. My Note actually became so hot after these benchmarks on LP that I shut it down immedaitely afterwards. Not warm, but actually hot (this in a room at about 15 C). Running Samsung JB it is usally cool to the touch and occasionally gets slightly warm. Perhaps there is a happy medium range that doesn't lead to such experiences? I would hate to run this in a hot climate (I once killed a £1300 laptop by trying to save a few pennies on AC in Bangkok... ha ha lesson learned).
I will do some more tests this evening or tomorrow (family day out today) and will include raw kernel.

This values should not harm your device. I'm using it for a long time, and also with many hours of cpu stress testing. The overheat protection values are not changed.
see http://forum.xda-developers.com/galaxy-note/general/antutu-benchmarks-nightowl-lp-12-1-vs-t3093720 for antutu benchmarks (ongoing).
