Does EGit use .git/info/exclude? [message #1076036]

I've just started using EGit to work with a local repository on a project that has a large (VERY large) number of files, some symlinked from a NFS, that get created in the local repository, but should be totally ignored for the purposes of git operations: checkout, commit, branch, etc.

I've added the directories to the .git/info/exclude file, and git operations from the command line work as expected: I can throw a new local branch, checkout to switch between my local branches, etc.

Everytime I use EGit to do similar commands though, the operation hangs. Taking a stack trace shows things like:

"Worker-6" prio=10 tid=0x9d400800 nid=0x6c80 runnable [0x9d3fe000]

I suspect that egit/jgit is walking a directory structure that I really want it to just ignore, and which I've put in to the exclude file for that reason. Is that the case? How should I be telling egit not to look at those directories?

It's correct that JGit walks ignored directories and then ignores them. It's a performance bug.
