227039 - Widgets significantly slower than almost all my other applications

Status: RESOLVED DUPLICATE of bug 91351

(Core :: XUL, enhancement)

Description

[Matthew Cooke]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20031103
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20031103

Although the UI responsiveness on both linux and windows is bearable I find that
the widgets are quite sluggish by comparison to almost all my other programs.
For example all my windows programs on Win200 and all my GTK/Gnome programs on
Linux are significantly faster. It just gives the feeling that mozilla is slower
than other programs even though the rendering may be faster.

Reproducible: Always

Steps to Reproduce:
A particularly easy way to see the difference is just to click on the File menu
and move the mouse across the menus so they flick up and disappear quickly. In a
windows or gnome application the menus are fully responsive in mozilla the
rendering often doesn't even keep up with the mouse movement.
Actual Results:  
On any other application this is lightening quick. On mozilla/linux in
particular this is noticeably slow. Annoyingly netscape 4.1 seems more
responsive on my 120mhz machine than Mozilla 1.6a on linux on my 2.4ghz machine.

Expected Results:  
Mozilla widgets, in particular menus should run at the same speed as widgets in
other application not several times slower. It gives the application a feeling
of having much worse performance than it actually has.
