My company recently switched to an i386 Ubuntu 8.04 LTSP server (2 quad-core CPUs, 8GB RAM, hardware SCSI RAID) from a K12LTSPv6 x86_64 server (2 dual-core CPUs, 8GB RAM, hardware SCSI RAID).
I've noticed that our 3 timed load averages now hover around 1.25, whereas on the older server, the load would rarely top .3 --- We have LDM_DIRECTX=true by default, so I assume the jump doesn't have anything to do with on-the-fly SSH encryption. I'm worried that it has to do with PAE & the bigmem -server kernel. I know that load average reflects the number of processes waiting in the queue, and that a jump in # of CPUs will make the load average artificially high, however 1.25 seems really high. Any ideas why this is? Using dstat -C I can state the most of the 8 recognized CPUs are consistently idle.
