Current Wisdom on NFS/CIFS Checkouts & Working Copies

What's the current wisdom on doing checkouts to NFS and CIFS?
I'm seeing general checkout times of a given repository in the 2 second range for local disk, and that jumps all the way up to a minute and a half or more going over CIFS or NFS (Windows 2008R2 fileserver, running OpenText NFS for the NFS side), in either 1.6 or 1.7.
An 'svn export' of the same repository to the same mounts hovers around 20 seconds, revealing that 'checkout' is doing a lot more work that's not going well over the remote mount.
This subject doesn't seem to come up very much, and I may have missed the key post that would answer this for me. I'm aware from my research that Subversion may had been attempting certain locking operations, and also tended towards a lot of file renaming/duplication that made it less than efficient over NFS/CIFS.
Thanks for your time!
