OK. Instead of going over all of the usual questions again, can you point
me to a previous mail in which you explain your observations and test
results in detail?
The most recent is http://marc.info/?l=freebsd-stable&m=119428719505129&w=2, but
it started way back at
http://marc.info/?l=freebsd-current&m=118998090512027&w=2.
I've tried a lot of stuff in between, and all I've been able to narrow
it down to is that it's not a display driver issue, and that none of
my swap partition is getting used, so that's not the problem. During
compiles, my UP system with ULE still gets very unresponsive when
compiling, sometimes taking up to 10 seconds just to draw a new terminal
window. Even changing focus with the window manager can take several
seconds. I'd like to provide more info, but I'm not sure what stats
are useful for this particular issue. Please let me know.
dmesg is at http://redundancy.redundancy.org/dmesg.txt, and kernel
config is at http://redundancy.redundancy.org/DEEPTHOUGHT. Even though
I'm still getting reported 80-95% memory utilization and no paging,
I'm going to get an extra gig of RAM on order to see if that improves
things. 2G of ram for a desktop, what's the world coming to? ;)
OK, can you obtain a schedgraph trace when the problem is manifesting?
See /usr/src/tools/sched/ and previous discussion in this or related
threads.
