I upgraded my Notes to 8.0.2 2 weeks ago and it works fine for me. Overall, it performs better compared to the 8.0.1 I have been using over the past few months - and it didn’t crash often. However, when I upgraded to 8.5 public Beta 2 yesterday, my Notes client/Domino designer has been crashing and it took me 8 seconds or more to open any emails compared to the 3-4 seconds performance I had when I was using 8.0.2. Anyone have any idea how to improve this? I thought 3-4 seconds is a bit slower than 1-2 seconds performance in my R6 client for opening emails and that is still tolerable. However, 8 seconds is a bit too slow to tolerate on daily basis. For me to open any design elements in the new Eclipse designer also took a long time. Help please, anyone?
Subject: you are using beta software …
what do you expect? 
seriously, I do not think all of the 8.0.2 performance enhancements are in 8.5 beta 2 but will be in the release version. You really have two options 1) stay with what you have or 2) go back to 8.0.2 and wait for the final release
