IDE Startup Time

One thing I noticed after I installed Irida 5.1, I found that the startup time is much slower. So I tried to clean up CDS in JDK 1.5 and found that it made the startup time to be much faster. You guys can try executing the following commands while you don't have intellij running.

C:\PROGRA~1\JetBrains\IntelliJ IDEA 5.0\jre\bin>del client\classes.jsa
C:\PROGRA~1\JetBrains\IntelliJ IDEA 5.0\jre\bin>java -Xshare:dump

Let me know whether it helps or not.

These commands rebuild the class shared archive. I can't see why this would speed up the startup time -- java generates this archive the firest time the VM is launched, and automatically rebuilds it when necessary (if ever).

I don't know why but it seems that CDS generated from IDEA installer wasn't generated properly in WinXP environment. So when I did that, it improved the speed tremendously.
