Hi. This is my first message to a mailing list (I hope I am doing this
right and emailing a friendly audience).
I recently started using LyX and am finding that LyX can be very slow
when I
have a moderate sized document (eight pages or so) with lots and lots of
mathematics equations. I am using Windows XP on a 3ghz laptop with more
than a gig of ram so I am not sure why it is so slow. Whenever I type a
letter it can take more than a second (or seconds) to appear in the
document. Has anyone else experienced this issue? Any known solutions?
Thanks,
Ken
It works fine for me (no discernible delays) under XP on a 1.5 GHz
laptop with 768MB of RAM (and that's with instant preview on ... it's
faster without instant preview, of course). Based on a sample of size
two, we can conclude that your laptop has too much power for LyX. :-)
More seriously, if you are using instant preview, you might try turning
it off. If that cures the problem, I would take a look at the LaTeX
(MikTeX?) installation, since IP does lots of little latex runs in the
background.
A couple of grope-in-the-dark suggestions follow. First, you might try
opening the task manager (or something better, such as Process Explorer,
if you have it) and keeping an eye on it while you type in LyX. It
might point to something else (firewall, antivirus program, ...) eating
CPU cycles while you're using LyX. The other possibility would be to
run LyX in debug mode and see if the (torrent of) messages tell you
anything about what's going on. You can start LyX in debug mode from a
DOS prompt (in the LyX bin directory). Start with
lyx -dbg
which will give you a list of all the debug options. The omnibus choice
is lyx -dbg any, but that will give you a nonstop flood of debug output.
You might want to start with a more selective option.
