I recently upgraded to 8.0.1 and my projects take a very long time to load while files are scanned. IDEA seems to cache information about the latest project and loads that quickly, but I switch between a number of development source code branches of a large project; whenever I switch, it seems to incur a wait of several minutes. One factor that might be influencing IDEA is that the project has the same name in each branch.
I don't remember having to wait this long with 7.0.x.
Are there any options I can tweak to encourage IDEA to cache more (more space or more projects) to avoid the long wait while loading projects?
