filepro on multi-core processor

[Fairlight]

Symmetric multi-processing (aka SMP) tries to balance processes (or
threads) evenly between cores.

filePro is a set of single-threaded applications.  Each binary only uses
one thread.  One copy of clerk will only use one core.  One copy of report
will only use one core.

However, if you are running concurrent binaries, those will be spread out
evenly across the cores by the OS (unless someone did something silly, like
set binary CPU affinity to a single core).

Honestly, CPU is the least of the issues. filePro is disk-bound for
performance, not CPU-bound.  Well, until it 'crashes' with an error which
prompts you to hit Return, when it likes to eat everything it can doing an
infinite polling loop on STDIN on *nix.  (Not sure how it handles its error
"Press Return to continue" waiting on Windows, but I can't imagine it's
likely to have been done any more elegantly.  Barring that scenario, disk
speed is way more important than CPU speed where filePro is concerned.
