I created a folder with 5001 files in it ... maybe that is not enough?
 I just used small simple text files as I was only checking for the
general problem in managing the temp files and the WC metadata.

Upon checkout (using 1.6.15 command line client) I did not notice any
slowdown.  Windows checked out via HTTP across internet in about 49
seconds as opposed to 33 from my Mac (which is a faster system).  The
main thing is checkout did not seem to slow down.

I did a similar test, using 5100 files in a single directory.  Each file contained only the content "file XXXX" where XXXX was the number of the file (so tiny files).  My linux system took 17 seconds, while Windows took a bit less than 2 min (but Windows is virtualized while linux is on the hardware).  I also did not notice a slow-down as the checkout proceeded.  Both systems used 1.6.15 and accessed the repo via https.

I did, however, notice that the time to *add* the files (done via svn add *.txt) seemed to progressively slow down.  But this was only observed by watching the files in the console as they were being added (it was relatively easy to see the rate because the each file name had a linear number at the end).  I don't have any timings to back this up, though I'll collect some if anyone's interested.
