...last night I decided to try enabling SCHED_ULE (ULE scheduler). I followed the directions listed in the FreeBSD documentation. The only changes I made to the configuration was to change the scheduler and to comment out a few network cards that I know I am not using.
The build went fine, no errors. After install I rebooted and got a slew (went by too fast to really catch them) errors and other messages (I know one was it could not load the screen saver and another was a problem with the sound driver). So then I rebooted, hit unload and pointed to the old kernel and ended up having some problems with that as well (which turned out to be unrelated - ISP issue - I am going to become a network guru at this rate with all the dhcp, tunneling and other network problems I've been having - not all are problem with PC-BSD either, btw).
So, I reinstalled from scratch again. At least I am getting good at reconfiguring everything just so. Altho' I noted: after installing the second patch, my fonts got kind of scraggly looking on the Konquerer start page.
Anyway, thanks again for a great distro! OH YEAH! My question... I am guessing it is not as simple as just recompiling the kernel with PC-BSD is it? Has anyone done it? I would like to try running ULE but do not want to go through rebuilding my entire system again.
...well, I seem to be a dope. I cannot do anything right the first time, but I do, at least, learn.
Anyway, despite building a generic FreeBSD 6 kernel with ULE, instead of using the PC-BSD config, it is working. The first thing I've noticed with the CPU monitor is that it is a lot more "busy". Not in the sense that more stuff is going on, but asmon zips up and down (or back and forth I should say).
Not sure if it really seems more responsive if you have a lot of stuff going on, but it seems as tho' it recovers more quickly if there is any hesitation.
No crashes yet.
I also have not tried tunneling (pptp) since the new kernel build... I'll go try that now. Anyway, it all seems fine and dandy!
...I went back and built via the PCBSD configuration file. Very nice! I get it now... PCBSD loads a lot of items as options? Well, whatever, none of the extra error messages and what-not and it is working fine as ULE at the moment.
