Intellij Idea 9 slow response on typing.

Question

I'm using IntelliJ Idea 9 on a windows 7 box - 2GB RAM. I'm facing this strange issue where the response of the editor is very slow. When typing, the characters seem to appear after a delay.. and gets annoying after a point.

However, IDEA 8 on the same machine works perfectly.

Would like to know if someone has faced this earlier.. Or is there any recommended solution..

Thanks.

Answer 1

You should try the 9.0.1 RC build available at http://www.jetbrains.net/confluence/display/IDEADEV/Maia+EAP, some performance problems were resolved there. Also ensure you don't have third-party plug-ins installed.

If the issue remains, refer to the instructions at http://www.jetbrains.net/devnet/docs/DOC-192.

EDIT: IDEA 9.0.1 has been released, please use the latest available release build.

Interesting, in my case the issue was having the Project and Structure windows open, and having scroll to/from source enabled probably didn't help. Closing the palettes sped up editing for me.
