Hi Tim,

Either this is due to a slow computer or Klyx is slow.

A slow computer can be caused by a hardware problem, including bad
spots on your disk or a mostly full disk, or by resources gobbled by
other software. I can tell you that in my experience, KDE is a resource
hog. Also, most browsers are resource hogs, especially if they have a
lot of tabs open.

Slow Klyx can be caused by slow LyX or by the KlyX implementation being
slow.

The easiest test you can make is to save and archive a file that
exhibits this symptom, power your computer off, then power it on, and
before running anything else, open your saved file with Klyx. Leave the
archived version alone. Either the symptom gets less severe or it
doesn't. If it does, send us the output of:

lscpu
vmstat
df -h
lsof | wc -l

Those will help determine whether you're just too underpowered for KDE.

If the symptom is unchanged after powering off, install plain old LyX,
open the saved (not archived) file in LyX, and see whether performance
is noticibly better. If so, sounds like KlyX is a problem.

Just for fun, temporarily try using LXDE instead of KDE, and let us
know if it makes a big difference.
