Ok, to reproduce this I created a testrepository, added a folder with
692 files in it and committed.
When I now browse that folder with the explorer, it first 'hangs' for
about two seconds (while fetching the status), then the overlays appear
all at once. That means, the 50 visible files get their overlays shown
within less than a second. I even activated the SVNStatus column, but
that didn't slow down explorer either.

What you describe here (about 5 overlays per second) looks like some
kind of race condition, but I have no idea where it comes from.
Do you have another instance of explorer running? Maybe even showing the
same folder?
