OT Setting CPU Affinity

[Sean Bruno]

Sorry for the Off-Topic here, but I am testing FC2T3 on a Dual-Proc
machine and wanted to try a different test.

Is there a command line application that can be used to lock a process
on a single CPU or logical CPU(HyperThreading)?  I am running into a
performance lag with a Java app that seems to manifest itself under
multiple processors.

Well, answered my own question...Seems that Robert Love created a
utility(set of utilities) called "taskset" that allows you to override
the scheduler and "lock" a process to a specific CPU.

Take a look at `run`.  I've been using it since FC1.
