I've noticed 4.5 to be quite a bit slower than previous versions. This seems to be the case across the board -- compiliation, cvs checkouts, switching between source files in different tabs, etc. In fact, if it weren't for the 1.5 support I'd go back to the previous version. One thing I always liked about IntelliJ was that it has lots of nice features but it felt rather light and speedy. Now I feel a bit like I'm working with an early version of JBuilder.
Is there anything I can do about this?
