Fricas it's another CAS based on Common Lisp.

BTW, the current SBCL versions are much better than the stable/oldstable releases such as the ones for Debian or Ubuntu LTS.

Try Fricas, you might like it too.

On Maxima, beware, because your package manager might ship you a Maxima version built with generic and unnoptimized CL compilers.

GNU CLisp's performance against SBCL it's abysmal. On an n270 netbook, MCClim widgets built from Ultralisp (QuickLisp repo) run in realtime with SBCL. ECL it's a bit beter, closer to SBCL than CLISP. CLISP fails to compile due the lack of threading support on 32 bit. And even if it ran MCClim, it would run visibily redrawing widgets like Win32 ones under a Pentium as they did back in the day.

Thanks for the suggestion - will look into it tomorrow.

Not performance heavy here. What I do require is something that is less buggy though. Maxima has zero to no test suite so there are regularly stupid regressions that break everything.
