[IE] Excessive CPU usage

Click for full size
For the last couple of weeks my IE9 has been taking forever to open to a usable screen. I am opening 5 sites automatically.

In above shot, 24% usage is not that much, unless it goes on for a l-o-n-g time. Mine

I have deleted browsing history and temp files.

Dell DXP061, Core 2 6300, 1.8 Ghz, 3GB memory, Win7 Ultimate.

Any ideas?

TIA.

Are you a member of any of the clubs here at DSLR ? Depending on the type, a high CPU usage is to be expected.

Supposing you have a 4 core system, that 25% means it's pinning one entire core.

What's the page that's causing the issue?

Dual Core. No virtualization.

This is what Aero peek looks like when its hung. Hard to tell if one web site is causing the issue.

What does the Performance tab of task manager look like?

The way you tell which site is causing the issue is open them individually.

This is the performance tab about 15 Secs after starting IE9.

Well, you need to follow process of elimination to isolate the cause. Deconfigure those automatic home pages for the moment (you can always put them back later) and experiment with opening IE to about:blank, then trying the individual pages to see which one is the offender.

I know this is not exactly what you recommended, and I will try that, but I pinged each of the web sites. Smartmoney was the longest at 245 ms average.

High ping wouldn't bog down the browser instance, what would do that is a lot of / broken / poorly implemented dynamic scripting.

Can you remind me how to flush the DNS cached?

Thanks.
