176689 - Tickers on pages result in high system resource utilization

Status: RESOLVED WORKSFORME

(SeaMonkey :: General, defect)

Description

[Joe]

Certain pages, home.netscape.com have tickers (CNN News in this case) that seem
to hog system resources.  I get either an intermittent spinning multicolor disc
during which the page cannot be accessed or a continous spinning multicolor disc
that requires force quitting Mozilla.

Joe, what mozilla build are you using?  Do you have the java or flash plug-ins?

Comment 2

[Joe]

Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.2b) Gecko/20021016

I'n not sure how to check the plug-ins.

Revising summary.

Comment 4

[Joe]

That's a crock.  Utilize so much system resources that force quitting Mozilla
becomes necessary, that's normal and acceptable?  

Comment 5

[Greg K.]

Joe, what are you talking about?

Comment 6

Greg, what I'm talking about refers to my original posting of what I considered
a najor bug.  That being that certain pages that utilize Shockwave Flash or
simple tickers (like the CNN ticker on the netscape page) bog down my system
mercilessly.  I get a multicolored spinning disk, signifying extreme resource
utilization that most often requires me to FORCE QUIT Mozilla and try to
remember to avoid the page that caused me to have to force quit.

Aza commented that high resource utilization was normal and basically blew off
my concern.  Now, I'm no expert by any stretch of the imagination, and I can't
even say for sure that I might not have a HW problem, but I doubt it as Mozilla
is the only app with which I have a problem.  So, why is it that IE handles
these pages without problem, but Mozilla does not and when I report the problem,
I'm told it's normal?

<http://home.netscape.com/> does have a JavaScript ticker, but performance seems
fine viewing it using FizzillaMach/2003021203 on my 466-MHz desktop G4 running
OS X 10.2.4.

Joe, can you still reproduce this problem using a current nightly build? What's
your hardware/OS X version?

Unable to reproduce with latest Mac builds on 10.1, 10.2 or 10.3. I get no hang
at several sites with tickers and other js animations including
http://archive.bclary.com/dynamicdrive/cmarquee/ and several real-world cases. I
cannot reproduce a hang on my old G4 450.
