In response to your Flash suggestion and Jeff Stickland's suggestions:
The problem mostly seems to be pages that run some kind of ongoing
process that when poorly done eat a lot of time. It appears it's not
Flash or java script. To explain:
Two excellent examples, one is easy to check, one is not:
http://www.npr.org/templates/story/story.php?storyId=13
This is the site for the NPR radio show Fresh Aire. Just recently they
added a regularly scrolling list of tweets to their tweet page. Every
time it scrolls it spikes cpu to about 80-90%. Averages out to 10% of
cpu time for this one page. I've run into one other page, forget where
now, that had smooth continuous scrolling of such a list and it ate
100% of cpu time.
The other example is any page for the Arizona Republic web site
azrepublic.com. Some pages run scripts and about once a week some page
apparently has a bad script and it runs for about 5 minutes till IE
pops up a msg that a script on the page is running slow and should it
be stopped. Until that msg pops up the page will hog 100% of cpu time.
Memory shows about 25% or 1/2 gig of physical memory is still
available.
This NPR scrolling list is not flash or java script. Turned them both
off, went to the page, and the scrolling happens anyway.
Amazingly as a test I went to a web tv page (CBS) and watched a hi-res
(that is not grainy like youtube) about 640x480 video and flash and
the IE process for the page only ate about 20% of cpu between the two
of them. And I use flash for news videos, instructional videos, web
tv, so I don't think I'll turn it off. This NPR site also has a flash
ad, but turning off flash so it's a static ad only reduces cpu time
less than 1%.
Turning off page refresh doesn't help either. Set it to never, went
back to the NPR page and, out of cache, the flash ad and the dreaded
scrolling list did their thing and ate up the same cpu time.
So that's my story. When I find cpu is way busier than it has reason
to be I want to be able to know which page, which tab, is doing it and
stop it. Or even if I can't tell which, I'll just go to each tab and
stop it (if I could) till I find the biggest culprit. Just stop, do
nothing, sit there and look pretty like a screen shot. I can press F5
when I want to check if anything's new. There has GOT to be a way to
do that. No?
Thanks
