RE: Poor performance in windows. Switching back to CVS

Actually, on that note: if the OP has their working copy on a FAT/FAT32
drive then this could cause problems. FAT only stores filestamps with a
2-second resolution, so unless software that compares timestamps knows
that and specifically ignores one-second differences in the timestamp
then they'll think the files have changed even when they haven't, which
in SVN's case would lead to performance loss as it needs to rescan the
contents of each affected file.

I don't know if SVN ignores one-second differences in timestamps or not,
so I don't know if it's vulnerable to this.

NTFS uses a much higher resolution for timestamps, so would not be
affected by this problem.
