[Gcl-devel] Re: cmpinit.lsp

[Camm Maguire]

Greetings!

1) Can you send me your file?  Pretty hard to help with so little
   information. 

2) Speed differences of this magnitude are almost always due to
   garbage collection.  (setq si::*notify-gbc* t) to find out.  Also
   look at (si::gbc-time) and its info page.  If so, make sure you
   declare the types of your variables where possible.

3) gcl-2.6.1 and above comes with a profiling option.  Compile with
   --enable-gprof, then bracket your code with (si::gprof-start) and
   (si::gprof-quit). 

4) I don't know what your lisp is, but I'm reasonably confident that
   your performance issues are far more basic than those related to
   fine tuning compiler switches.
