So then the reason it works in ST2 is because ST2 does not index files.
How much ram do you have on this machine? I wonder if you machine can’t handle keeping the index of all 100,000 files in memory?
Have you tried moving a few folders to see if 80,000 files works ok?
Are some of these 100,000 version control files? If so, have you set them to be ignored?
Have you tried checking out another really large project to see if it happens with that too? Using SVN to checkout something like svn.apache.org/repos/asf/subversion/tags/ should give ST3 plenty to chew on.
