Hello, I'm running FreeBSD 4.2-REL on a box dedicated for newsfeeding. The server specs are PIII733/1024MB Ram/Adaptec 160/7x Seagate 18GB disks. The problem is the load. The load averages are between 20-30!!! I've started a discussion at the Diablo list, but they couldn't find anything strange. The machine is working, currently 30Mbit/s input and 80Mbit/s output, it's much, but shouldn't affect the load that much. On a previous server (PIII450/256MB RAM/Adaptec 2940) the load was around 2, which should be normal (also a bandwith eater..). I think the problem is the Adaptec 29160 (PCI64) adapter in combination with FreeBSD 4.2-REL. Or a kernel option I've forgotten ;) The server mainboard is a Micro with a ServerWorks chipset and 2 processors slots (only 1 used). I've disabled as much as possible in the kernel, even the SMP options (should these be enabled...). I've also enable softupdates on the spool and set the maxuser to 512 in the Kernel. An "iostat -d 1" looks good. Below I've attached the dmesg and a top. Please let me know if I've forgotten something or if you have any other options!
