There's good information about NTFS wrt subversion here:
http://superuser.com/questions/15192/bad-ntfs-performance

I found FAT was 10-20x faster than NTFS for the lock/unlock working copy
operation, but I never saw a case where it was logarithmically slow or
appeared to get slower as it went on.

It's easy to test this. Install ImDisk from here:
http://www.ltr-data.se/opencode.html/#ImDisk which is very
straightforward (no reboot), and create two virtual disks, format one as
ntfs and one as FAT32.

Then compare the timings between the three (the third being the physical
disk).

The differences are magnified when the amount of actual work to do is
small compared to the time required for the lock/unlock operation, eg an
svn update when nothing has changed on the server.
