Firefox use 99% CPU when viewing RescueTime Dashboard
Greetings,
Viewing RescueTime's dashboard maxes FireFox CPU utilization using either FireFox 2.0.0.12 or FireFox 3.0b4. First it draws the graphs nice and cleanly, and then spikes up to 99% and sits there.
I'm using Shockwave Flash 9.0 r115. (More plugin info below...)
The page hauls my browser to a halt; it's unusable afterwards. It happens every time.
Extensions in Firefox are:
Adblock Plus (but RescueTime is green-lit)
CuteMenus - Crystal SVG (just a menu hack)
Firefox Showcase (but not in 'continually render' mode)
Google Notebook (but not open)
Nuke Anything Enhanced
Session Manager
Web Developer
Plugins in 3.0b4 are:
Adobe Acrobat
Google Updater
iTunes App Detector
Java(TM) Platform SE 6 U3
2 Microsoft DRM plugins
Mozilla Default Plug-in
QT 7.4.1
Shockwave Flash 9.0 r115
Windows Media Player DLL
It doesn't appear to happen with IE7.
Hope this helps!

Heheh-- Unfortunately, our users don't usually have your geek-fu, my friend!
I think we'll probably have to remove the transparency of the flash objects as a short term fix... (wmode transparent is what allows our calendar div to float on top of the flash stuff-- it's a z-axis hack).
Bargh. Certain does not "advance the cause", but probably needs to be prioritized.

Hey Morgan!
Many thanks for the detail.
Hrm-- We've been tracking this issue for some time-- I believe it's related to the number of flash objects on the page. It's been repro'd by the vendor we use for charting and they opened a bug with Mozilla ( https://bugzilla.mozilla.org/show_bug... )... Which seems to be getting very little attention.
Here's the third page of the thread where they most recently posted an update:

(sigh)
I'm going to try to pull the spark charts to reduce the flash objects on the page and see if that helps. I'm also going to dig into the new crop of visualization stuff that Google just released to see if we can wean ourselves off of FusionCharts.
I’m wanting to be mad at someone, but can't figure out who!

Inappropriate?Greetings,
Heh! Okay; I futzed with it a bit, turning AdBlock Plus back on for rescuetime.com, and nuked the goal lines (HBullet.swf), for example, and the CPU utilization cleaned right up.
I got about the same performance benefit from nuking the two sparklines at the top, but nuking the one big 'Time Spent' didn't have a big effect.
With the bullet lines for the goals removed, it returns to being relatively snappy.

Inappropriate?Greetings,
Hrm... I thought wmode="opaque" would also allow the CSS to float on top of the flash, and some comments have it using lower CPU. Not something I've played with, though, so you'd know far better than I.
But I know the feeling of 'does not advance the cause'...

I’m unsure

Inappropriate?hi everyone.
I too have battled this issue of Firefox using 100% CPU when showing Flash on a webpage in wmode; transparent.
I've blogged the issue here:
http://www.campjohn.dk/wp/?p=753
so far I ONLY find this issue on Firefox, if anyone can tell me differently, please tell me
