my last tests on patched (3.0.4 + migrate.c fix + vserver) kernel produce full cpu load on dual 8-cores opterons like on this htop screenshot -> http://pluto.agmk.net/kernel/screen1.png afaics all userspace applications usualy don't use more than half of physical memory and so called "cache" on htop bar doesn't reach the 100%.
the patched kernel with disabled CONFIG_TRANSPARENT_HUGEPAGE (new thing in 2.6.38) died at night, so now i'm going to disable also CONFIG_COMPACTION/MIGRATION in next steps and stress this machine again...
