Mosix did not perform well for me doing kernel compiles. The network
latency was too high since there is so much disk IO on all the small
files. Mosix really shines at parallel distributed applications that are
number crunchers.  For a compile monster, SMP is the processor
arrangement to use as it is able to use disk IO better. It is almost a
linear speed up per CPU.

 SCSI Ultra320 RAID drives at 15K RPM on a PCI-X bus make nice disk
subsystems :) Some motherboards have a dual PCI-X bus so one can spread
the the load around onto a mirrored raid 5 system. That gets twice the
read speed (but only single speed write).
