One way to track the problem down would be to build LyX with symbols
and profile it using kernrate, the free Microsoft sampling profiler, to
find out where the hotspots are. Unfortunately I'm not set up to
build LyX, and I don't have time right now to pull the sources and do
that. (I'm not sure I have the disk space required, for that matter.)
Hello Michael,
I've downloaded this kernrate program but it looks awfully complicated
and I don't have much time right now to learn it. If you know how to use
that I could send you a LyX 1.5 package with full debug symbols if you
would like to help.
I managed to have this report on a lyx-1.5 with full debug, someone
understand something about it?
Abdel.
