Svn generates a *lot* of file system operations during checkout,
update or similar. I don't think they're asynchronous, so latency is
sure to be an issue. Networks have much higher latencies than local
hard disks. In your case the pain is doubled because you're getting it
coming (checking out from the svn server to your local machine) and
going (writing to the development web server via SMB).
Under these conditions, how could performance *not* suck?
I experimented along these lines once (keeping my working copies in an
eclipse workspace on an SMB share) and running eclipse locally under
windows. Boy did that stink. Running eclipse remotely and just
displaying it on the windows box is *much* *much* better!
