pre7-8 still isn't completely fixed, but it is better than pre6.
Try doing something like 'cp -a linux-2.3.99-pre7-8 foobar' and
watching kswapd in top (or qps, el al). On my dual-proc box, kswapd
still maxes out one of the cpus. Tar doesn't seem to show it, but
bzcat can get an occasional segfault on large files.
The filesystem, though, has 1k rather than 4k blocks. Yeah, just
tested again on a fs w/ 4k blocks. kswapd only used 50% to 65% of a
cpu, but that was an ide drive and the former was on a scsi drive.[1]
OTOH, in pre6 X would hit (or at least report) 2^32-1 major faults
after only a few hours of usage. That bug is gone in pre7-8.
[1] asus p2b-ds mb using onboard adaptec scsi and piix ide; drives are
all IBM ultrastars and deskstars.
