That doesn't seem to make much difference, nor would I expect it to. (The
cache it refers to is nothing to do with TSVN.)

Am I right in my interpretation of your stats that the main fact is:

4860 files in one directory - loads very slowly.
3078 files in one directory - loads *much* more quickly.

If so, I think this probably caused by TSVN's icon overlay cache timing out
between the two sizes. Once this happens, there is a complete collapse in

There are various hacks and bodges in the code to try and avoid this
happening, but I don't think they're based on deep statistical analysis,
and they probably still have various pathological cases.

I am currently writing a completely new status cache, which I hope will
address all sorts of issues in this area. Don't expect it for a week or
too though, I'm afraid.
