I'm having this problem with firefox 1.07 and opera 8.5 on a via 800mhz cpu.

Has anyone noticed that the cpu goes to 40% to 100% whenever a website showing a javascript text marquee starts scrolling? If I move
the mouse to it to make it stop, the cpu normalises. I don't want to have to turn javascript off, but I can't think of any other way to block those marquees.

here's an example site http://fantasy.premierleague.com/

I am assuming a liveCD or frugal install.

With this happening across two different browsers, I suspect it may be the following...

The size of Cache and the fact that Cache being in the home directory, thus, ramdisk. Therefore, as the Cache fills, ram fills and then system starts to thrash from ram to swap. Perhaps moving Cache to a real hard drive would improve performance when hitting these intensive sites. Or possibly adjusting Cache size.

20mb cache on a hard disk did not help.

okay, did some googling, and it seems it could be one of several phenomenons to do with either the gecko rendering engine and/or the Xserver used.

maybe https://bugzilla.mozilla.org/show_bug.cgi?id=230409
or related to this thread; http://kmeleon.sourceforge.net/forum....t=5549.

no fix yet but quite interesting though, win98 seems not to have it while linux,2K & XP do, depending on your xserver or graphic card.
