298422 - Extremely poor Firefox performance on the linked site

Status: RESOLVED DUPLICATE of bug 112738

(Firefox :: General, defect)

Description

[IU]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050621 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050621 Firefox/1.0+

The linked website has a script that is doing who know what, and Firefox pins
the CPU at sucks up an additional 110-120 MB just to render the site.  Internet
Explorer, on the other hand loads the page pretty right away and with negligible
memory consumption.

Reproducible: Always

Steps to Reproduce:
1. Monitor Firefox in Task Manager while you visit the linked URL.
2. Also do the same as Step 1 using Internet Explorer
3. Notice the difference.

Actual Results:  
My system slows to a crawl as Firefox pins the CPU and sucks much RAM.


Expected Results:  
I would expect performance similar to how Internet Explorer handled the site.


My system:
Intel PIII 933 MHz
512 MB RAM
Windows XP SP2 + full patched

I must be getting really tired.  There are more grammatical errors in my bug
report than in a typical ESL student-authored report. :-) Here's a corrected rehash:

Maybe related, but not duplicate.  Notice that there is also a script involved
in this case.

Loading the URL still uses (about) the same CPU time and memory when I disable
JavaScript so I don't think a script is causing this bug. 
The page loads in under a second when I remove all '<' and '>' from the
preformatted text as described in bug 112738 comment 5.

In that case, I'll mark it as a dup.  However, shouldn't this almost 4-year old
performance bug be fixed by now?
