next in thread | raw e-mail | index | archive | help
I've used 5.0-RELEASE for few days now, and I've been experiencing some
serious performance problems. I haven't had the time to examine it more
closely, and frankly, I have no clue where to start looking for. Perhaps
someone knows what this is all about.
Description:
Every time machine is under heavy load (CPU, network, disks) it
completely jamms for fraction of a second for every ten seconds or so,
everything just stops and then continues. I noticed this while compiling
software and copying files over NFS while listening to MP3's, later
realized it wasn't just MP3's that lagged, but the whole machine,
including console and everything.
Hardware:
dual p3 800MHz on Abit VP6
512MB RAM
Tekram DC-390U2W
SCSI-only (IDE-controllers disabled from BIOS)
SB Live!
3c905c NIC

Won't paste it all here now, but it's been stripped down to be as light
as possible.

I hope someone could bring light to what's going on. Alltho I'm not whining,
I knew what I was getting myself into when I installed 5.0, it would be nice
get things solved, for FreeBSD's sake already.
