We use Subversion with all of our FSFS repos mounted over NFS. It 
works fine and is fast as long as NFS caching is enabled. OTOH, we 
have gigabit Ethernet between the server and a NetApps filer which 
has several gig of disk cache. Our remote NFS accesses are faster 
than typical local disk accesses, though a local RAID array might do 
better with good hardware.

I think NFS caching is reasonable to use in our setup where only a 
single server accesses the repos. But it might not work so well if 
more than one server is used or if clients ever try to access the 
repo directly. With NFS cache turned off, Subversion client 
operations are many (~10) times slower.

Also make sure the NFS file locking is enabled and working. This is 
vital. Not all NFS servers support this, so please check carefully.
