I have high CPU usage in one of a few iexplore.exe *32 processes that i see in Windows Task Manager. Is there a way to identify which tab causing CPU spikes just like it is possible in Chrome?

Windows 7 64-bit Enterprise
Internet Explorer 9.0.8112

Try closing tabs one-at-a-time. Whichever one you close that causes the CPU to stop spiking is the culprit.

Highlight the iexplore.exe *32 process that has the high cpu usage and hit the "end process" button, it will close the offending tab.

Hopefully you can see which tab was closed by watching IE, this will work unless you have too many tabs open making it difficult to observe.

As a test, I suspended the high CPU usage iexplore.exe in Process Monitor, then went through the tabs in each IE8 to find the frozen ones. This process could probably be simulated with program that suspends iexplore.exe with highest CPU usage over few seconds, then sends some window message that IE should normally respond back to each of the processes. The one that doesn't respond was the frozen one and then you could unfreeze it and query the window title or something like that.

A short and sweet autohotkey_l ahk script to do this might be interesting exercise. I just have too much on my plate already.
