I've set up freebsd 4.4-RELEASE mashines running on IBM x330 series hardware. Both with SMP support compiled kernels, apache 1.3.22 and php 4.0.6 with sybase support to connect to an ms sql server. Both have 2 NIC online, one to get over a bigip loadbalancer to the internet, and one internal for database link. Both are running fast and stable, but sometimes the load goes up to 20,30 or even >140 for a few seconds and then comes relativly fast back down to an avg of ~0.5. So the question is, why ? Both mashines have 1GB of RAM, a 1GB swap partition, two 866PIII procs and an adaptec U160SCSI controller, which accesses a 9GB U160 disk. I also attach the kernel config file.
