[TriLUG] Multithreaded Apps

[Josh Vickery]

I've always liked SMP systems, but for a while they were considered to
be a bit exotic.  Now with multiple cores on a single chip becoming
the norm, everyone gets to see the benefits.  SMP doesn't ensure that
applications will run X times as fast (X being the number of cores)
but it does ensure that the computing experience will be more
pleasant.

As for 64bit, I don't think you will see much of a performance
improvement there on a workstation, unless you have some reason to use
more than 4GB of RAM.  There is no harm (aside from a slight potential
degradation in performance) in running a 64bit chip in 32bit mode, and
it might make your life a little easier during this transitional
period.
