Well, 15 seconds is really long but that might be partly due to your
PC being a bit outdated.  It is true, though, that loading CL-PPCRE
takes some time because at load time some hash tables are created (in
util.lisp).  This takes longer on CLISP because CHAR-LIMIT is quite
high there and because CLISP is sometimes a bit slower than other
Lisps.  For example, on my laptop CLISP needs about 2.4 seconds to
load CL-PPCRE while LispWorks takes less than 0.3 seconds.

You can save a custom image (this is implementation-specific) that
already includes CL-PPCRE.  If you do that you won't have any problems
with the load time anymore.  (Note that creating a "stand-alone"
binary usually also involves creating a custom image.)

Does that help?
