I am using IntelliJ (Community Edition) for several months, and at first I'm pleased about its speed & simplicity. But now, after upgrading to version 10, it's extremely slow. Sometimes I click a file then it takes 5 - 15 seconds to open that file (it freeze for that time).

I don't know if I have done anything which cause that: I have installed 2 plugins(regex, sql), and have 2 versions of IntelliJ on my machine (now the version 9 removed, only version 10 remains).

Is there any tips to improve speed of code editor, in general, or specifically IntelliJ? I have some experience when using IntelliJ: 1. Should open IntelliJ a while before working, cause it needs time for indexing.

Don't open too many code tabs
Open as less other program as possible. I'm using 2 GB RAM WinXP, and it just seems fairly enough for Java, IntelliJ & Chrome at the same time.
