[slime-devel] presentations and xemacs very slow?

[Todd Sabin]

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
