Since I switched from idea-4.5 to idea-5.0, I've been having performance problems. There are long delays sometimes after making minor code changes. I did turn off the options to save files and reload on frame activation. I also tried increasing the allocated memory in idea.sh. Nothing helped.
This is a large project with hundreds of jar files, but it worked fine in idea-4.5. For now I'm going back to idea-4.5, but it would be nice to know if this is normal.
This is on SuSE-Linux-9.3 using Sun java version "1.4.2_07".
