Yes.

As long as you want to compare different Lisp implementations on the
same OS you should be fine.  If you want to compare across different
operating systems note that the tests also output the number of
repetitions and the time for each test so it should be relatively easy
to tweak this a bit and get what you want.

Don't forget that those benchmark tests use GET-INTERNAL-REAL-TIME
which isn't perfectly accurate.  You should probably use TIME and
measure user and system time.

If you come across interesting results please post them here.

Cheers,
Edi.
