Issue 3476: Massive CPU/lag spikes in 0.3.154.3 http://code.google.com/p/chromium/issues/detail?id=3476
New issue report by [EMAIL PROTECTED]: On both my work and home machines (both dual-core, lots of RAM) I've experienced a new issue with 0.3.154.3: massive CPU load while scrolling certain tabs. When this has reproduced, it's been on http://www.shacknews.com/latestchatty.x . The trigger may be some particular Flash ad being loaded at the top of the page (?), which is why it's so hard to reproduce this at will; it could also have to do with navigating back and forward between pages (maybe something isn't getting cleaned up properly on navigation?). CCing jam/ananta (for plugins) and brettw (for navigation controller) in case they have ideas. The behavior I see is that scrolling the page, with either the wheel or scroll thumb, suddenly becomes _horribly_ laggy. The Chrome task manager shows the renderer process for that tab (not the plugin or browser processes!) taking tons of CPU (>50% almost immediately on scrolling, and continuing to spike upwards as I keep scrolling). (By contrast, when the problem is not occurring, dragging the scroll thumb as fast as possible continuously gets the renderer process up to a peak of about 40% CPU -- seems kind of high to me, but the app remains very responsive.) At this point the browser is nearly unusable, as any time I try to scroll the tab my machine basically comes to a dead halt. Restarting the browser definitely fixes the issue. No more data yet.
