NFS veryyyy slow over VPN

["Dr. Michael J. Chudobiak" <mjc@xxxxxxxxxxxxxxx>]

Hi all,

I have a Windows 2000 machine that accesses various local and remote 
(via a Sonicwall VPN) FC5-server NFS shares, using Windows Services for 
Unix.
The shares on the local network behave well, but the ones over the 
remote VPN are slow and tend to freeze Windows Explorer when doing 
simple things like listing directories. FC5 clients that access the 
remote VPN share behave better (they pause for a few seconds, but then 
come back to life).
Does anyone have tips for making NFS work more gracefully for remote 
Windows clients? (If not, maybe installing Unison on a local FC5 would 
work better...)
