The svn client manipulates many small files within each .svn/
directory. Because of differences in operating systems and
filesystems, client operations (particularly those that do lots of disk
i/o, such as 'svn commit' and 'svn update') are about twice as slow on
windows as on unix-like systems.

This is a well-known fact among developers, and there's really nothing
we can do about it other than rewrite the whole working-copy library --
which is a distant 2.0 task.

The only psuedo-workaround is to have users work with smaller working
copies on win32. That is, don't checkout gigantic projects and then
run 'svn up' or 'svn commit' from the root of the working copy.
Checkout smaller subsets of the project, or run the commands on smaller
sub-trees when possible.
