I have just got the latest stable tree via sup and performed a make
world and also made a new kernel.
Everything is fine with my system until the loading gets to the point
where it is starting to swap and then it performs appallingly. The
paging code sounds like its writing out at a byte at a time to the
disk! If I have three active processes at this time then the system
starts to thrash:-( The last kernel I compiled was on the 10th of June
and did not notice any problems with that.
Here is the output from top when the performance is just about to go
through the floor.
load averages: 1.45, 1.28, 0.94 17:19:09
85 processes: 1 running, 84 sleeping
Cpu states: 3.5% user, 0.0% nice, 13.2% system, 2.7% interrupt, 80.6% idle
Mem: 19M Active, 22M Inact, 5360K Wired, 264K Cache, 6242K Buf, 96K Free
Swap: 102M Total, 4396K Used, 98M Free, 4% Inuse
here is the output from dmesg
