There are no script components, and removing the CSS doesn't speed things up either ... It seems to just be a slow table rendering problem ... Reproducible: Always Steps to Reproduce: Load page and view how slow it is to render. Actual Results: Page is slow. Expected Results: SHould be zippy! I will upload a zipped version of hte file, including the original and a variant that has all CSS explicitly removed.
Created attachment 117874 [details] ZIP file of slowly rendered page, and associated image files. ZIP file with slow page. The file testpage-noCSS.html has all the CSS removed, and also has <table border="1"...> set so the table borders can be viewed.
Page is fast on Linux trunk build 2003-03-19-05. Windows-specific? Graphics-card specific? Ian, what graphics card and driver revision are you using?
works as fast as ie 5.5 for me using mozilla1.3 on win2k try removing the body background image and then retesting.
Hmmm. I'm at home now, and tested Mozilla 1.3 under Windows 98 SE, and the page rendering is snappy -- no problems at all. And my machine at work is much faster than the one at home ..... So it must be something about the Win2k box at work.... I'll check again tomorrow, and pass on more details (graphics card, H/W, etc.). But really, on my Win2k box, it is truly awful .....
Ok, The example testpage-noCSS.html from the attached ZIP file is still very slow. However, if I remove the background image from the first <table> element then it is fast. So the problem may have someting to do with overlapped images / transparency. I will attach a revised ZIP file containing three test documents: testpage.html -- original (slow) page testpage-noCSS.html -- CSS removed -- still slow testpage-1.html -- changed testpage-noCSS.html by removing main background image. Now the page is fast! My win2k machine: IBM Thinkpad T22, PIII @ 800MHz, 256MB RAM, Graphics: S3 Savage/IX (8MB). running in dual mode (LCD and CRT).
Created attachment 118010 [details] revised set of examples demonstrating slow page redraws.

Ian, i would try to reproduce the problem using the latest mozilla1.4. some image related bugfixes were checked in by firstname.lastname@example.org. it may have been solved.
I just tested this on my Win2k box using the Mar23 nightly build (2003032308) -- the problem appears to be gone. The page is now fast and responsive, with none of the sluggishness seen in Mozilla 1.3. Many thanks to email@example.com for the patch -- whatever it was! I will keep this open until the 1.4beta, and then test and close the bug if it's still fixed?
( .... ok, so I was a bit remiss in retesting on 1.4). Anyway, I've retested using MOzilla 1.6 and 1.7RC1, and see no rendering / performance problems. So I am marking this bug fixed.
