McCLIM performance with CMUCL under SLIME

Sunday, October 3, 2004

Several weeks ago I described the recommended setup for initializing CMUCL multiprocessing when running McCLIM under SLIME. But with this setup, there appears to be a slight McCLIM performance degradation, at least with the software combination I use: latest McCLIM and SLIME CVS sources, CMUCL 19a branch, and GNU Emacs 20.7.2 under Debian Woody.

The performance degradation manifests itself, for example, as a slight response delay when operating a pull-down menu in a McCLIM application. I have tried disabling the multiprocessing initialization by setting slime-multiprocessing to nil in ~/.emacs, and removing the #+clim-mp reader macro in ~/.swank.lisp. This way, response times of pull-down menus feel better, i.e. instantaneous.
