Something like yes! Maybe not a dialog, as I use things that peg my CPU (games) somewhat frequently. One idea we toyed with was marking such tabs as 'on fire' (icon or color), so at least there was a visual indication. I think this would be a good starting point before anything more obtrusive like a dialog or bar.

[chromium-dev] Re: detecting tabs using a lot of CPU?
It's better to be non-animated. Remember,ichrome is using too much CPU already. Second; the user is doing something, he doesn't want to be distracted with information unrelated to his current task. If the user finds himself waiting on his current tab, his eyes will probably see a tab being slightly burnt and will wonder what is happening. :) M-A On Wed, Oct 7, 2009 at 1:13 PM, Darin Fisher da...@chromium.org wrote: http://tinderbox.mozilla.org/1afi003r.gif On Wed, Oct 7, 2009 at 10:10 AM, Glen Murphy g...@chromium.org wrote: Something like yes!

[chromium-dev] Re: detecting tabs using a lot of CPU?
You could replace the favicon with a spinning clock or something. It might also be interesting to provide indicators for high memory usage (or perhaps if the recent memory growth is high), or IPC issues. Then again, many users might prefer not to have their tabs attracting attention needlessly. I mostly don't care whether a tab is using lots of CPU. -scott On Wed, Oct 7, 2009 at 10:10 AM, Glen Murphy g...@chromium.org wrote: Something like yes!

We had also discussed putting icons indicating audio into tabs. That sounds crowded with icons, though: imaginably a game could have facicon, Unicode symbols, CPU load, audio, and the x displayed.

[chromium-dev] Re: detecting tabs using a lot of CPU?
I'm not convinced that we should bother users with this kind of stuff. If an advanced user want to see what's consuming resources, they can open the task manager. If we want this for debugging, perhaps it should live behind a flag. It would be cool if some kind combo of dev tools + extensions could allow developers to be notified of conditions like this.

It'd be nice to have a non-distracting visual indicator, but to play the devil's advocate... What about intentionally CPU intensive sites that use canvas, video, WebGL? What about scenarios where it's a plugin that's gone haywire? Could this be accomplished by an extension that displays a little CPU graph?

But when you have other cpu-intensive tasks running in the background (and I had) such a tab drains the resources. The technical side (exposing the info to extensions) doesn't seem too hard. I'm thinking about implementing it. I'm not sure about the UI. For me it could be even something on the extension shelf (support for that already exists).

Umm... shouldn't we be looking into why the tab is taking so much CPU? :) For example, back in April I saw a similar thing happen on Facebook and with WinDbg found that WebKit was simply running in an infinite loop. The WebKit team jumped on this and submitted a fix just 2 days after I reported it ( https://bugs.webkit.org/show_bug.cgi?id=25312). - Finnur.
