How to make project scan faster

[Ulf Zibis]

Hi, please help.

Initially opening a OpenJDK project in NetBeans is very slow. It takes 
more than 2 hours. Also later operations are often very slow.

IMO the problem is, that Netbeans scans the whole amount of JDK sources.

I'm looking for a solution, where I only checkout the sources of 
interest to the workspace source folder.
- how to only checkout sources from Mercurial repository, changed since 
date of bootstrap JDK snapshot?
- how to force NetBeans to rely on the binaries from bootstrap JDK 
snapshot in scanning the project, so it must not compile the whole JDK 
sources behind the scenes while scanning?

BTW: I'm working on Windows XP.
