Subject: test [PATCH] 2.1.91pre2 swap clustering
Date: Thu, 26 Mar 1998 14:01:52 +0100 (MET) [thread overview]
Message-ID: <Pine.LNX.3.91.980326135818.523D-100000@mirkwood.dummy.home> (raw)
Hi Linus,
I have some test results on 2.1.91pre2 now. With my patch,
it's a tad agressive, but _extremely_ fast with swapping.
I think it would be wise to reduce the number of tries by
a factor, as in:
- tries = (50 << 3) >> free_memory_available(3);
+ tries = (50 << 2) >> free_memory_available(3);
The clustered swapout-from-application seems to work fabulously,
since the program moves the disk arm less then it used to.
Rik.
