Speed up Intellij IDEA startup time

Intellij IDEA 8 has become a big IDE and takes quite sometime to startup. Here are a couple of hints to improve startup time:

1. replace idea.exe.vmoptions contents with the following one:

-Xms400m
-Xmx800m
-XX:MaxPermSize=120m
-ea
-Dsun.awt.keepWorkingSetOnMinimize=true

increasing the RAM size allocation even more if your machine can handle it, e.g. to 1024m

2. modify idea.properties by moving the config directory to a faster drive if e.g. you home profile is saved in a network drive, e.g.:

# idea.config.path=${user.home}/.IntelliJIdea80/config
idea.config.path=D:/Config/.IntelliJIdea80/config
