I have a small sized J2ee project with around 5,000 java files. Since upgrading to Idea 4.0 I have had nothing but issues with performance. My machine is a P4 (1600) Dell D600 with 512mb ram.
To be specific I have the following problems:
1. Idea cannot keep up with typing. I type and there is a lag between ALL keystrokes sometimes longer than 1 sec!
2. Compilation usually fails and I have to restart. Why does Idea insist on recompiling my classes after I get a clean CVS project even though my ant build scripts compile using the debug option? Can't Idea recognize my projects classes are good to go? This rebuild take ~ half an hour and fails 20% of the time.
3. 4.0 seems flaky. Everything is slow. Project setttings add new source path takes 45 to 60 seconds to bring up the open file dialog!
4. Not a performance issues but how do you turn off the blatently buggy quote " code complete? Try pasting in a sentance with quotes in it and you will see what I mean. The developer must have been on crack when they implemented this feature.
I have tried netbeans and eclipse using the same project and they have no issues with performance in regards to compilation and typing. Wow imangine being able to type and have a computer keep pace!
The company I work for has purchased 12 licenses at considerable expenses. I am now at the point where I have to consider throwing away our investment and switching to eclipse since it is almost as good as Idea in the feature department but is considerably faster. Idea 4.0 reminds me of my time with Kawa and their last release just before folding as a company. Too many peolple relized the expense was not worth the product over and competing cheaper (or free) IDE's.
