Could you please use 'Profile Me' feature and send us snapshot ? It would be very very helpful. Thanks in advance.

I have re-installed patch 2 in order to profile the reported behavior but guess... i can not reproduce it!
I will now stay using patch 2. If the problem appears again i will make an ide profile snapshot and report it.

Thanks.
Until it can be reproduced, I'm resolving this as works for me.
Please reopen if you manage to reproduce it and when you have a profiler snapshot.

Can you please specify what exactly is slow? What action you do and it takes too long?
In the snapshot I see just heap walker (Classes view) retrieving all classes and their instance counts - this takes nearly 4 seconds, since it takes some time to calculate and transfer all this information from the target virtual machine to debugger. Unfortunately, this retrieval is running twice, but it's not clear whether it comes from two user gestures or not. No other debugger action is visible in the snapshot.

Please specify what are the actions that you see as slow and which steps can we do to reproduce it. Thanks.
