Subject: Re: [PATCH] Recent VM fiasco - fixed
Date: 10 May 2000 02:29:09 -0500	[thread overview]
Message-ID: <m366smx3qy.fsf@austin.jhcloos.com> (raw)
In-Reply-To: "James H. Cloos Jr."'s message of "09 May 2000 23:05:01 -0500"

Ok.  Tried w/ Manfred patch (ie the 2nd half).  kswapd still uses a lot
of cpu doing recursuve cp(1)s, but it is less than in virgin pre7-8.  I
got about 10s of cpu for cp and 40s for kswapd doing a cp -a of the 7-8
tree (after compiling) on the ide drive (w/ 4k ext2 blocks).  On the 1k
ext2 block scsi partition, it was 1m50s for kswapd and 20s for cp to cp
three such trees.  kswapd %cpu never exceeded 65% on the latter and 50%
on the former; substantially better than in virgin 7-8, but not as good
as earlier kernels (though I don't have any numbers to back that up). I
did this test in single user mode w/ only top running (on another vc).

Hope the datapoint helps!
