This is a little nitpicky, but if Explorer is taking a long time to
display a directory, there's a good chance it is spending most of its
time doing UI operations (composing widgets), not FS operations.

That doesn't change your overall point--that we should pick a shard size
which makes browsing into an svn backend acceptably fast under Explorer.
But realize that we're now tying the tuning of the svn architecture to
the performance of particular GUI tools, not to particular filesystems.
