XFS 100% CPU utilization when viewing email in Evolution
Last modified: 2008-05-01 11:38:04 EDT
Description of Problem:
When viewing email in Evolution XFS uses 100% CPU utilization and there is as
much as a twenty second delay before the email is displayed.
Version-Release number of selected component (if applicable):
Stock RH 8.0 XFS, couldn't find a version, maybe it's Xft 2.0-1 calling itself xfs?
At will and on demand. Seems to depend on the email. A simple text email
doesn't seem to have a problem, but a complex email with fonts and colors takes
a long time
Steps to Reproduce:
1. open any font/color rich email in Evolution
I can send an example email if needed, but almost any will do.
xfs is the X font server. Xft is a library for doing fonts without
having to talk to the X server or X font server.
Most likely this is an evolution issue of it asking xfs to do
a lot of work.
I installed the MS Web fonts package trutype fonts in ~/.fonts/ and the "lag"
went to less than a second and CPU utilzation stayed low. A huge difference
from 20 seconds and 100% utilization. Looks like Evolution was making XFS look
for fonts that didn't exist then timing out or something. Anyway, the web
truetype fonts in ~/.fonts/ seems to make the problem go away.
It's actually probably just picking fonts which X renders slowly. This is not
an evolution bug at least. If you'd like to follow up further on it, please
file a bug against XFree86.
