Netbeans is nice, but I am actually in the process of leaving it for straight emacs. Netbeans stalls out, is a memory hog, and crashes nearly daily for me right now. I also found that I really only use it as a SVN GUI, and file manager. I the code completion is slow and never useful to me, many of the auto complete features are just annoying. My Ruby tools like autotest, irb, debugger, and rake tasks are just more responsive on the command line (some don't really work at all inside Netbeans).

I really liked it for awhile, but I started realizing that I didn't use or really like most of the advanced features, and all the work it does trying to provide those features are makes it slow.

Do anyone else's Netbeans seem to index things for the first hour the program is opened?
