Status: VERIFIED DUPLICATE of bug 166932

(Camino Graveyard :: General, defect)

Description

[Itay Neeman]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.1a3) Gecko/20060622 Camino/1.0+
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.1a3) Gecko/20060622 Camino/1.0+

I've been having this problem since Camino 0.9. When going to http://www.ynet.co.il on OS X, Camino's processor usage goes up to 90% usually making the website very slow. It does not happen on the article pages or any other page on YNet except the main page.

This also happened in Firefox 1.5.0.2 on OS X.

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.ynet.co.il
2. Open activity monitor and look at Camino's CPU usage


Actual Results:  
Camino CPU usage up to 90%

Expected Results:  
Camino should not have such high usage just displaying a page.

This si a default installation of Camino.

Itay, what kind of machine are you on?  (Model/Processor/RAM)

Comment 2

[Itay Neeman]

I have a Quad Powermac G5 with 2.5gb of RAM, running OS X 10.4.7 (but this happened in all previous versions since 10.4.3).

It looks like it's the ticker on that page; I know there's a similar filed bug.

Comment 4

[Robert Lindsay]

It is the DHTML stock ticker, in fact. What's interesting is that that page is also largely unusable in Opera 8.54. The page runs great in IE. The webmaster is an idiot who is making an IE-only page. BTW, the stock ticker that causes such high CPU horrors in both FF AND Opera (yes, in Opera the CPU also goes nuts) works great in IE. The comments are cut off and not visible in Opera and lately the articles are too. Furthermore, the embedded videos only work in IE. I am having to fire up IE just to use the page, and I almost never have to do that. Who is the webmaster, Bill Gates.?

Confirming bug on PC Windows 2000 - forget the Mac-only business. I don't think it has anything to do with the Mac OS.

Furthermore, this is apparently an evangelism issue.

Robert,

I just don't see how comments about who designed the page are relevant ot this issue at all.

1. I've used the page on Firefox on Windows, Linux and OS X, and it worked fine from there. I could see the movies on both Windows and OS X without any problems (I never tried on Linux).

2. Yes, the page is probably designed for IE, and yes, that's not a good thing.

3. BUT, despite (2), there are very very few things on a webpage that should be able to make Camino or Firefox spin to 90% processor usage. I'd rather that Camino fail to render the page than stall the entire computer - that's just unacceptable. If it failed to load the page, then it would be the pages fault, and an evangalism issue. But if Camino stalls my computer, that's a progamming bug - not an evanglism issue.

Please only reply if you have something to add to the bug, not to just to vent about Microsoft or IE. Thank you.

It's yet another dup of bug 166932

I agree with this. Actually, there are *many* bugs with Ynet, and a number of them have to do with high CPU use, and many of them are on Windows, if you read the comments. It often seems to revolve around that DHTML stock ticker that the page links to - it is an external file. There are a number of bugs about marquee scrollers and DHTML scrollers and tickers causing high CPU use on a number of pages, not just this one. The latest comments from Moz folks are saying that the DHTML ticker bugs are all evangelism issues. However, as you note, they tend make Moz crawl, halt or temporarily freeze, so that to me is not an evangelism thing. Evangelism, as you note, should just be giving us no page at all, not whacking out performance.

Problem is apparently either fixed or much better in the latest version, 1.5.04 on Windows 2000.

Comment 9

[Stuart Morgan]

There are very specific, known reasons why this issue is especially bad in Camino, and this bug has been duped accordingly.  Firefox behaviors should be discussed in another bug.
