View Full Version : SP5: 100% CPU usage on Digg

Ever since upgrading from SP4 to SP5, I've been having problems with Digg.com. I click on a link to a Digg article in my newsreader, but when the page has almost finished rendering, OmniWeb beachballs and tries to consume 100% of the CPU for about two minutes. Then suddenly everything is normal. I click on a different article, and the same thing happens all over again. Rebooting didn't fix it. Has anybody else seen this? (PowerBook G4, 1.2GB RAM)

I saw a similar (potentially identical) issue in SP7 visiting http://digg.com/gaming/Introducing_Nintendo_Wii. Upon load, OmniWeb beachballed. I didn't check the CPU usage, and I Force Quit far before 2 minutes.

Yeah, I'm still having the problem in SP7. I load up any digg page, which renders fully, but then I get a beachball and 100% CPU usage for 20-30 seconds, then everything is fine. No other site does this; only digg. And it happens every time I go to digg.

I get this too, FWIW (in SP7).

Still a problem in SP9. :(

Turned off Java and Javascript and still had the problem. Not sure what's up there.

And in SP10. I did some more investigating and confirmed that it's a WebKit issue:

I don't know how to link two threads, but I have now confirmed that digg.com leaves some residues that result in anywhere from 5-20% idle CPU usage by OW after one leaves digg.com. The amount of CPU usage depends on who long one spends on digg.

Safari, however, does not suffer from this.

Both OW and Safari do take a long time to process the digg pages.
