Results I have seen are broadly comparable ---
SBCL is faster, ECL compiled is a little slower, Clisp is much slower,
ECL interpreted is much, much slower. Sorry I don't have numbers.

Anyway being a little bit slower than SBCL is very good and
it is certainly fast enough to make ECL a workable option.
