Last time I looked gcl ran the testsuite faster than all other lisps.
Which is not to say gcl is fastest for all problems.
If you want to run your code with sbcl or cmucl, (or clisp or
openmcl/clozure or ecl), you have to build maxima yourself. Not hard if
you have autoconf and automake. Just run bootstrap, configure, and make.
