If those were PC's you would look for VISTA (VIruses, Trojans,
Spy-ware, and Add-ware) stealing cycles.

Are the Macs connected to a network?

A couple weeks ago my WinXP system became sluggish and started giving
"Windows delayed write failed" errors. The initial diagnosis, after
ruling out VISTA or a bad disk, was a bad network adapter, but after
replacing the mainboard twice, and trying different ports on the ethernet
switch, I swapped the system for another PC and got the same symptoms.
It turned out the network interface (set to autonegotiate) was running
100/half while the switch was coming up 100/full. Now that I know what to
look for, I found the another PC on the same switch with the same problem.
Linux on the same PC's was also sluggish (copying files by ftp maxed out
at 40kB/s).

People pay a lot of attention to user interface experiences, but hardly
any attention to diagnostics to determine why a system seems sluggish. In
my experience (heavily weighted to unix and PC's), hardware failures,
network infrastructure issues, VISTA, and disks at 99.6% of their capacity
are all common reasons for users asking for new machines (e.g.,
substandard performance with their existing machine).
