One thing I just noticed is that kmem_flags in the kernel on my machine was set to enable kernel memory debugging. Over 200 MB (and growing) was held in the kmem_bufctl_audit_cache. Performance became sluggish the more I used the machine. Adding "set kmem_flags=0" to /etc/system and rebooting fixed the problem. After the reboot check kmem_flags with mdb. It now should be zero. root at prae> echo "kmem_flags/D" | mdb -k kmem_flags: kmem_flags: 0 Doug This message posted from opensolaris.org
