Description Ilya Tikhonovsky 2011-08-29 11:34:09 PDT 
I'm profiling Network panel refresh metod.
1) open an url with a number of resources.
As example http://dolboeb.livejournal.com/?skip=60 this page has about 600 resources;

2) open inspector's network panel;
3) open inspector for inspector;
4) start cpu profiler in the second inspector;
5) refresh and wait until load event is fired
6) do the step 5 n times

WebInspector.NetworkLogView._updateOffscreenRows eats 14sec but all its children less than 1 sec.
Almost all the time was spent in native call this._dataGrid.scrollContainer.scrollTop;

Closing as invalid, as this bug pertains to the old inspector UI and/or its tests.
Please file a new bug (https://www.webkit.org/new-inspector-bug) if the bug/feature/issue is still relevant to WebKit trunk.
