Within the past few months there has been a McCLIM performance
regression: drawing a very large class graph with the CLIM Listener
takes about 15X longer than it used to.  With guidance from Christophe
Rhodes I did some benchmarking and tried to locate the possible cause,
but I didn't get any useful results.

I don't know whether your Climacs responsiveness problems are related
to this.

You might try using CMUCL instead.  A few years ago CMUCL produced
code twice as fast as SBCL's.  SBCL has been greatly improved since
then, but on your slow machine using CMUCL might still make a
difference.
