Well, I can confirm that after installing the SR1 Optimizations early patch I can see a noticeable improvement with regards to switching between tabs and opening xml documents, at least on this Windows 7 machine I'm currently using. Thanks for the links!
As for the leakiness/stressfulness towards the GC of the ADT plugin, I agree, a large part of the issue surely resides inside it and is only masked by this optimization patches (but at least the toolbar button flicker is gone as far as I can see so it could really be that a large part of the problem was caused by inefficient calling of plugin listeners by the IDE, which were unnecessarily being called multiple times from different code-paths and causing the stress). I tried tracing it myself once, but don't remember anymore where exactly I got stuck with it... Anyway, it seems like it's working better (acceptable) now, so thanks again! It was slowest on the macbook, so I'll post my feedback once I get around to trying it on there... On Tuesday, January 29, 2013 1:35:34 AM UTC+1, Nobu Games wrote: > > Just as additional information.
