High CPU usage on web page with Phoenix 0.4 (build 20021108)

Jugalator · Post by **Jugalator** » November 13th, 2002, 12:46 pm

I happened to get to this swedish site (not that I watch the crap known as Fame Factory). What caught my attention more than the actual site, was that the CPU load (on a P4 1.6 GHz, mind you) immediately got noticeable and was shown to be at around 40% according to the Task Manager.

The site: http://www.aftonbladet.se/noje/famefactory/

This 30-50% CPU load is regardless of the tab open as well. I still have the high CPU load when typing this post, as I have the site open in another tab in the same instance of Phoenix.

After loading the page it drops back to 2%...

Weird, the page loads correctly and all that, but if I close it, I go to 0% load. I reopen and immediately get at least 30% again??

Update: Could it be because of the flash thing? Hover your mouse at the title image. Your mouse pointer will leave a trail after it. Perhaps that's very CPU intensive for some reason? But I get the slowdown even if not hovering the mouse there

I tried and the mouse cursor doesn't leave a trail

Not in the 0.4 Milestone and not in the november 12-build

Sorry, RAF

On a 450MHz Celeron I have absolutely no problems on that page.

I open the page in background without surfing on it :

it use 72% of CPU, then drop to 30-40% until I close the tab (2%)

I use 0.4 pn WinXP (duron800-256Mo)

Hmmm, XP/NT specific bug?

Probably not platform-specific, I get a very high processor usage (50~60%) while loading and then 30% when it's done loading and idling.
That's on Linux Mandrake 9, running the 20021112 Phoenix nightly.

Try this one:

Really bogs me down in .4. Haven't tried a recent nightly.

Hmm, thatone keeps reloading data from the site for me

It makes the page get small jerking, though I guess since I'm sitting at a 10Mbit connection and download is basicly instant it might be a lot worse for slower connections(?)

It's probably some badly coded JS in the externally linked JS file, becuse turing of JS makes it go away.

Yes, they're doing something great: they attach a function to reload the page to the window.onerror event handler. Not really a good idea...

Hahahahaa!

That http://www.netformx.com site is a hoot!! Great programming job! LOL

I'm sorry, but I just thought that was pretty hilarious to watch the site constant reload every 1 second.
Using Phoenix 0.4 on XP SP1.

It works fine in Internet Exploder.

Yeah, that is what happens when people don't know what they are doing and only test their stuff in one browser.
