This bogs down processing of the initial surge in events when the inspector opens, and makes it feel unresponsive at first. If possible we should avoid doing sync layout work when handling messages in the initial few seconds, especially if it's redundant. We should batch the rendering using requestAnimationFrame and/or sending them over protocol from the backend. 1188672 1 webkit-bug-importer 2016-04-29 10:04:12 -0700 <rdar://problem/26006165> 1188698 2 nvasilyev 2016-04-29 10:41:46 -0700 This is going to be mitigated by bug 155629 "Web Inspector: Adding a new console message shouldn't modify DOM when the console log is hidden". Besides, I'm going to use requestAnimationFrame batching. 1189444 3 277916 nvasilyev 2016-05-02 11:44:39 -0700 Created attachment 277916 [HTML] Reduction 1189445 4 nvasilyev 2016-05-02 11:48:38 -0700 The attached reduction works pretty smooth.
