Hey John,
One more follow up and then it's bedtime for me. I wanted to further this
discussion just a little bit more by implementing the mmap solution that I
applied to perl to ruby instead. Now all of a sudden, ruby is much much
faster. My ruby source code follows:
Goodnight!
# ruby -W0
Hey Jon,
The most glaringly obvious thing I could recommend is that at least in your
perl routine (and probably the other languages) most of your time is
context switching reading from the disk.

I'm making mistakes.
The comparison should have been between both ruby versions ugh.
I'll let you play though. Have a great night.

It's not always beneficial. There are cases
