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. -JimC -- James H.
