Re: [RFC][PATCH v3 0/7] introduce automatic pool compaction

[Sergey Senozhatsky]

Minchan, FYI,

I re-done the test (untouched almost_empty waterline).


		Kernel log
test started [  788.064886]
test ended   [ 4025.914190]

test (doing `cp' in parallel):
(a) for i in {1..X}; do cp -R ~/git .; sync; rm -fr git/; done

# compiled kernel, with object files. 2.2G
(b) for i in {1..X}; do cp -R ~/linux/ .; sync; rm -fr linux/; done

(c) for i in {1..X}; do cp -R ~/glibc/ .; sync; rm -fr glibc/; done


Minimal si_meminfo(&si)->si.freeram observed on the system was: 6390


cat /sys/block/zram0/stat
   31253        0   250024      316 12281689        0 98253512   141263        0   141590   141763

cat /sys/block/zram0/mm_stat
3183374336 2105262569 2140762112        0 2821394432     1864   358173


The results are:

compaction nr:2335 (full:953 part:60956)

ratio: 0.01539   (~1.53% of classes were fully compacted)


More or less same numbers.
