TOP reports that Chimera is using major amounts of CPU time even when idle with no windows open. The %CPU reading fluxuates between 18%-90% with an average around 40%-60% Hardware: iMac 233 Rev. B/ 288 MB RAM Software: Mac OS X 10.1.5/ Chimera Nightly 6/14/02 Last minute update: It appears that terminating an active, background OmniWeb window displaying a flash animation caused Chimera's current CPU utilization to drop from ~60% CPU to ~30% CPU. I just confirmed that loading a page with flash (banners) in OmniWeb causes Navigator's CPU utilization to increase signifigantly. Loading the same page with Internet Explorer doesn't appear to effect Chimera. I'll have to conduct further tests to determine if the high idle CPU is also related to OmniWeb/Flash.
After quitting all browsers, re-launching Chimera and closing any open windows Chimera continues to utilize 80%+ CPU time.
Summary: High CPU usage when idle → High CPU usage when idle
The June 14 build idles for me between 0% and .5%. I see no problem.
This is due to Mozilla's continued usage of WNE rather than Carbon Events. Though CPU usage appears high, real performance is only minimally affected. *** This bug has been marked as a duplicate of 106689 ***
