Subject: Re: [PATCH 0/4] PM: Drop shrink_all_memory (rev. 2) (was: Re: [PATCH 3/3] PM/Hibernate: Use memory allocations to free memory)
Date: Sun, 3 May 2009 21:08:18 +0800 [thread overview]
Message-ID: <20090503130818.GC9661@localhost> (raw)

Hi Rafael,
I happened to be doing some benchmarks on the older shrink_all_memory(),
Hopefully it can be a useful reference point for the new design.
The current swsusp_shrink_memory()/shrink_all_memory() are terribly
inefficient: it takes 7-9s to free up 1.4G memory:
[ 131.899389] PM: Freed 1413380 kbytes in 7.03 seconds (201.04 MB/s)
[ 732.757916] PM: Freed 1490116 kbytes in 9.37 seconds (159.03 MB/s)
Below are the logs I collected by injecting printks. There are
basically two major problems:
- swsusp_shrink_memory() scans the whole 2G memory again and again;
- shrink_all_memory() is slow. It won't reclaim pages at all with
small priority values, because it's batching size is 10000 pages.
I wonder if it's possible to free up the memory within 1s at all.
(Maybe the slowness is due to too much enabled debugging options...)
Thanks,
Fengguang
