Hmm..
Perhaps the paging to/from swap is the culprit?
With 32 Mb my 3600 almost never uses swap at all:
nerdvax# swapctl -l
Device 1K-blocks Used Avail Capacity Priority
/dev/ra0b 64000 1 63999 0% 0
Having heard that the VM system changed in 1.3 I start to wonder
if things may go *boom* when you _do_ use swap a lot..
Bye Arno.
