I'll grant that I'm not running on a fast Mac (G4 450), but my overpriced JBuilder 6 (which I am hoping to be able to replace with IDEA) is quite responsive. I've evaluated 2.6 and it responds fine. But running EAP build 689 response is very slow. Clicking anywhere--menus, the edit frame, etc. takes ~2 seconds to respond.
My question is whether this is a characteristic of the JDK1.4.1 DP or whether this is just a result of the next version of IDEA requiring more horsepower?
