I open several windows each morning in SM 2.19, with several tabs in
each. These windows stay open about 10 hours day. CPU usage would be 3%
or so on my quad core XP machine.
Often, I noticed CPU usage of 30% or so by the end of the day. I saw
this problem before SM 2.19, but didn't track it down until recently. I
discovered this high usage was caused by two different web pages:
http://www.nytimes.com/
http://weather.rap.ucar.edu/satellite/displaySat.php?region=LWS&itype=vis&size=large&endDate=20061007&endTime=-1&duration=3
Closing these two pages drops the CPU back to 3% or so. I can also
prevent the ucar.edu page from using the CPU if I stop the animation by
clicking on the Stop button.
Is this behavior caused by the web page coding, or is it indicative of a
flaw in Seamonkey? My workaround is to Stop the ucar.edu page when I'm
not viewing it, and close the nytimes.com page when I'm not reading it;
interestingly, it's the Times home page that causes the problem, not
it's articles I get from clicking on links in the home page.
