HI,
I decided to get rid of my perfectly funtioning nexus 6 roms *mulitboot* and go back to decrypted ext4 format stock,
do benchmark tests, then unlock deencrypt, and go for speed test on f2fs.

So I got myself WugFresh tool kit for nexus 6, and the newest stock.

after successful install I only had a 23 gyg SD card... its a 64gyg device.

So I thought, take out verizon cut down sim? well that didnt help.

so I have to boot stock recovery and do a factory reset, Yeah back to 64 gyg

I do 3 tests, after i wait 5 minutes to make sure android has time to do whatever it does. bake in, download contacts, whatever.
I used androbench, antutu, and quadrant standard.

Sorry i dont have a better lay out or a graph, my presentation could use some work..
AndroBench:
test 1:
Sequential Read = 229.92 MB/s
Sequential Write = 75.51 MB/s
Random read = 20.11 MB/s
Random Write = 8.26 MB/s

Test 2:
SR = 160.58
SW = 74.42
RR = 20.37
RW= 8.35

Test 3:

SR = 230.65
Sw = 73.6
RR = 20.66
RW = 8.4

Quadrant Standard:

Test 1:13387
Test 2:12808
Test 3:13045

AnTuTu Bench

Test 1: 49895
Test 2: 49978
Test 3:49908




see screen shots.

Now I remove encryption via this : http://forum.xda-developers.com/nexu...2946715/page85

I do not notice much gain at all, however I post results anyway.

now I re ran same 3 tests, stock decrypted.

AndroBench:
test 1:
Sequential Read = 220.79 MB/s
Sequential Write = 74.27 MB/s
Random read = 18.59 MB/s
Random Write = 10.6 MB/s

Test 2:
SR = 233.97
SW = 74.78
RR = 18.53
RW= 10.23

Test 3:
SR = 236.29
Sw = 73.32
RR = 19.25
RW = 10.33

Quadrant Standard:

Test 1:13088
Test 2:13516
Test 3:13366

AnTuTu Bench

Test 1: 49776
Test 2: 49832
Test 3:49816


Now I tried F2FS as per : http://forum.xda-developers.com/nexu...6-rom-t3072917

and these are the results. it looks worse.

AndroBench:
test 1:
Sequential Read = 191.06 MB/s
Sequential Write = 76.83 MB/s
Random read = 18.58 MB/s
Random Write = 9.57 MB/s

Test 2:
SR = 208.12
SW = 76.27
RR = 18.22
RW= 9.56

Test 3:
SR = 208.04
Sw = 76.49
RR = 18.31
RW = 9.6

Quadrant Standard:

Test 1:12854
Test 2:13519
Test 3:13508

AnTuTu Bench

Test 1: 46036
Test 2: 46706
Test 3:45629

might feel safer with encrypted/password protected, wont boot without password... LOL and for a 10 to 20 mb/s read difference might very well be worth it
