With a network file system (either SMB or NFS, it doesn't matter), you need to ask the server for *each* of the following situations: * to ask the server if a file has been changed so the client can use cached data (if the protocol supports it) * to ask the server if a file (or a

So... I have two machines. My Fileserver is a core-2-duo machine with FreeBSD-9.1-ish ZFS, istgt and samba 3.6. My workstation is windows 7 on an i7. Both have GigE and are connected directly via a managed switch with jumbo packets (specifically 9016) enabled. Both are using tagged vlan
