[Asus Transformer TF700] sjgieson:
I inadvertently hijacked yugendreams thread a few days ago who was asking for which rom was the best. I stated I did not have good luck with Comi-X on my tablet and recommended going with Cyan Based rom instead. My reasons I stated were crashed reboots/performance of Cromi on my tablet.

This response was my opinion at the time and not very well articulated or well thought out, I admit. After that some discussion ensued and I told sbdags I would try Cromi-X again. In the former post I had stated it had crashed and sometimes I would factory refresh. I believe now (just guessing but pretty sure) the SDcard wasn’t seated properly and with data2sd enabled this was causing my instabilities. I have been able to duplicate the data wiped scenario by removing my SDcard. So this was likely the root cause of my stability issues as I had none my second time around (ran for about 24 hours). My first time through was with 5.1 and now I used 5.2 for what it is worth.

Full disclosure, I have biased toward AOSP roms, let me get that out of the way. I believe that ASUS, Samsung, HTC, etc. are hardware companies and the do a good job at what they do…making hardware. What they fail at is taking something a software company (Google) does and try to improve it. So any ROM that is based on a manufactures image I immediately have a little negative feelings towards it (how horrible the TF700T is stock vs Nexus 7 stock certainly helps solidify my claims). However I understand sometimes it is best to start with something that has been tested on the target platform and make it better.

So long story short, I ran a Androbench and Quadrant on my CMB (CM 10.2 base)/Bryce09 kernel which had better perceived smoothness/speed. I then backed up my rom, wiped in TWRP, flashed Crom-X (5.2a) selecting _Thatsv6 Kernel and mostly stock settings + data2sd. Rebooted and over the next 24 hours ran androbench and quadrant over and over again, I tried without DATA2SD with little to no difference and also Hunds kernel.

Here are my results comma delimited for each recorded run, sorry not formatted the best, I got lazy:

************************************************************************

Bryce/CMB (10.2/4.3 BASED, NO DATA2SD)

AndroBench Micro tests

SR: 14.33MB/s , 16.93, 13.37

SW: 78.37 , 171.93, 126

RR: 4.57 MB/s, 1171.42IOPS(4K), 4.29/1100.14, 4.25/1091

RW 143.63 MB/s, 36769.48(4K), 335.98/86012, 188/48079.03

Quadrant

Cromi-x 5.2/_that6-oc, DATA2SD

Microbench

SR:20.99,

SW:4.22,

RR:4.48/1147,

RW:0.47/121,

Little change on the subsequent test so failed to record, but super slow Random Writes….

Quadrant

4647, 4432, 4554

************************************************************************

Crom-x5.2/_that6-oc, NO Data2sd

No change on AndroBench MicroSD test, should have recorded but basically same as above…limitation in kernel?

Quadrant

4473, 4770 4642

************************************************************************

Crom-x5.2/Hunds Kernel

SR:17, 16, 17.38

RW: 50.6, 51.62, 47.12

Quadrant:

5432, 5235, 5337

All of the results were slower than CMB/Bryce09, now I am not trying to say one is better than the other here. In fact I think Quandrant score with CMB is still not as good as I have seen folks get here with Cromi-X. I have since restored my backed up CMB and am back to the faster results. Why are my Random Writes so fast with CMB with nodata2sd?

General thoughts, is there better benchmark tool to use….at this point I think I am going to say Data2SD is not needed regardless of rom….
