Subject: Re: Beginner question: performance problems with a simple program From: Erik Naggum <email@example.com> Date: Thu, 27 Dec 2001 19:48:17 GMT Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> * Janosch Zwerensky | The program works fine, except for the fact that I am not feeling well | about its performance speed-wise. Does anyone on this group have any | tips to offer regarding improvements in this respect? (I am working with | Allegro Common Lisp). Evaluate (excl::explain-compiler-settings) and turn on the various :explain options. The amount of output even exceeds CMUCL at its worst, but it can be very helpful in realizing when and how to declare stuff. What were the types of variables in the C version? How much time does a function call usually take? Do you have an example? /// -- The past is not more important than the future, despite what your culture has taught you.
