Hi, I decided to try out slime (been using ilisp), and found what seems to be a bug, or at least a poor default. I checked out the current CVS, and tried it in XEmacs 21.4.15 on an amd64 machine, with a semi-old cmucl snapshot (2005-01-04). Slime connected to cmucl just fine, but I didn't get too much further than that. Running buffer-menu made emacs hang for a second or more. After a little experimentation, I found that it hangs an amount proportional to the number of buffers I have. Once you get over 10 or so, you notice the delay, and when you get up around 50 buffers or more, it's really awful. I tried a bunch of stuff and found that this doesn't affect GNU-Emacs, and setting slime-repl-enable-presentations to nil is an effective workaround. I also tried the FAIRLY-STABLE branch, and it didn't seem to have the problem, but I couldn't get a connection to either cmucl or sbcl, so I'm not sure if that was a valid test. Anyway, does anyone have an idea what causes this, or if there's a better fix than disabling presentations? Thanks, Todd -- Todd Sabin <tsabin@optonline.net>
