I spent the morning downloading the trial versions of these products to
test their speed in comparison to the free implementations.  LW was very
fast, Allegro was still slow compared to the equivalent python program,
but faster than the fastest free implementation (Clisp).

I want to see how fast LW and cl-ppcre compare to the equivalent python
program (I think it'll be faster), I just haven't figured out how to get
ASDF working with it yet.  And I'm still hoping for some developer to
comment on my post to the SBCL user list as I'm stuck with the
open-source implementations.

LispWorks:
CL-USER 17 > (time (tester "/tmp/pgw-logs/trapd.log.ovnyc00p"))
