I bet it's just the disk I/O consuming loads of CPU power, with the added
effect of interrupts being disabled for a long time during disk I/O. 
Lost or delayed interrupts mean retransmits which are usually done with
exponentially increasing retransmit times (in TCP at least). 

Lots of RAM might help, but a faster machine (a Quadra with builtin
ethernet) should make a better server.
