I'm trying out Firefox again, and am dogged by slow performance,
particularly on startup and window/tab operations. The browser lags
noticeably, a feature it shares with Mozilla and a couple other apps
(most noticably OpenOffice.org). All of them share the characteristic
of opening to an initially unresponsive window which tends to show an
image of other desktop elements. Screenshot:

The terminal window (showing this email in progress) is duplicated over
the browser window. Note that the titlebar shows both blue and grey --
the grey bit is the part that's showing on the Firefox window.
Delays are noticed when:
- Opening new tabs.
- Loading new tabs in background.
- Opening new windows.
- Closing tabs.
- Launching the preferences dialog (Edit => Preferences).
Delays are up to 5-10 seconds, or longer, for actions to complete.
I'd chalked this up to Firefox itself being fundamentally slow, but
noticed on other systems that these issues don't appear to be present.
A few bits of extraneous data:
- P4 1.7 GHz 1 GiB RAM.
- As the wmmon dockapp shows, memory is roughly 50% free, and there is
effectively no swap usage. 'vmstat' shows no swapping during
actions.
- Graphics are XFree86 v4, with the 'sis' driver, on a "SIS 6325"
video card. From 'lspci':
0000:01:00.0 VGA compatible controller: Silicon Integrated
Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter
- Current display resolution is set to 1280x960.
- Stock Firefox theme. Numerous extensions loaded. System load is
~0.5.
Suggestions? Anyone else having similar issues?
Peace.
