I have this interesting behavior in the top utility on _both_ my 7.1
and 8.0 FreeBSD servers (updated to latest patches). The interesting
behavior happens only when my kernel is compiled with the ULE
scheduler. It does not happen when the kernel uses the old BSD
scheduler.
Here is a link of a

I think that's what you're looking for:
% sysctl kern.sched.name
kern.sched.name
have a stock 7.0 release.
I rebuilt the kernel with ULE scheduler, I think.
How can I tell if it is running ULE or 4BSD??

for a server setup as well (my server is also SMP), or is this something that
should be kept to a desktop?

My system is a "desktop" and yes I was previously using the 4BSD
scheduler.

Hi,
I decided to give the ULE scheduler a try a while ago (April 28).
when I last built 6-STABLE
Anyhow it seems great. I'm running a 2.4GHz Celeron with
512MB RAM and two 40GB, PATA disks. Right now I'm running
both a GNOME and a KDE session, I've got Thunderbird and

That's because you can't. ULE gives lower performance on the
workloads I have tested anyway. This may be fixed in the future.

Yes, in the workloads I have tested. Others have reported similar

I can't find any information on how to set the CPU affinity for processes in
the
FreeBSD 6 ULE scheduler.
On the linux box, which we're moving from, I have dual Xeon HTT's that I have
JBoss scheduled round-robin with the CPU affinity set to the first two
processors,
nice -15.

Hello!
I have some trouble with ULE scheduler. I have installed FreeBSD 5.3
When I try to use ULE scheduler (by editing GENERIC file), the message
"The SCHED_ULE scheduler is broken. Please use SCHED_4BSD" message
appear.
I do these steps:
