User Comments:
rosswald: deleted the entire project codebase and checked out manually (ie the files reappeared while NB had still project opened with old file list)

Comment 2 Ondrej Vrabec 2011-03-15 15:47:29 UTC 
Looking at the snapshot, it seems that the git support access IO for a bunch of folders through FileStatusCache.containsFiles()->FileStatusCache.getStatus() - this should be eliminated, the folders are not interesting in the scope of containsFiles and listFiles(), git does not track folders.
So calling getInfo() instead of getStatus() should be sufficient, information about files should be stored in cache anyway, so there's no need to involve isIgnored logic and sharability query.
