First step is probably to collect more data to find out whether the bottleneck is cpu, memory, io or network (although we can probably eliminate network here). Try running e.g. "vmstat 10" (its in the "procps" package which you probably have installed anyway) - this will emit a line every 10 seconds with interesting system information. (As a rule of thumb: ignore the first sample). Analyzing this can be a bit of a dark art - it requires a decent understanding of how the kernel works, but not too bad. Lots of people on this list should be able to help if they have that output. It's also worth having a glance in /var/log/kern.log (usually where syslog puts the kernel messages) for anything amiss: Misbehaving hardware can really mess things up. Hope this helps -- Karl E.
