Hello,
I use FreeBSD 6.1-STABLE #0: Mon Jun 12 18:00:56 CEST 2006
for a desktop (Launch several apps at the start and mostly nothing else, except when compiling). I've got 512 MB of ram.

From some time, I've noticed poor swapping performance -- this can be very annoying when memory needs to be swapped in and the whole systems chokes on disk I/O. Most frequently when launching a big application or clicking on recently not used application window.

What I notice, is that top(1) reports: 60 MB free, and 150 MB on the swap, which means these 60 mb are just sitting there doing nothing. I remember in older versions of FreeBSD tried to keep swap as little used as possible, leaving 3-4 mb ram free. This is just a feeling, of course, but it feels like it's slower now.

Can anybody comment on this?
Maybe there is a sysctl which can tune this ? (I've searched for such, but found nothing).

Best regards,
Marcin Koziej
