I'm using IDEA 4.5.4 (build 2253) and struggle with serious startup problems. When starting IDEA it takes about 10' (or more) until the "loading project" window appears, thereby making any interaction with other programs impossible. The scanning of files then takes from a couple of minutes to (guess) 20' depending on whether the project was updated from CVS before or not.
When looking for possible problems I found that the idea_home/system/vcs directory consumed more than 100MB. I switched off local histroy, restarted idea and cleaned the vcs directory. But IDEA took extremely long to start up again, thereby again building up the vcs directory.
My questions now are:
1. Is the vcs directory related to the local history? If so, why does IDEA build it up when switched off; if not, what are these 100MB for and how can I disable it?
2. Is there any relationship at all between the slow start up time and these 100MB?
3. What else can I do to boost the startup time?
Thanks in advance
Some rough numbers on the project I'm working on: the project consists of about 300 components whereof 130 components are IDEA modules, most of the others just libraries. The 300 components correspond to about 45k files (including resource files, excluding CVS files), the 130 IDEA modules result in 20k class files.
