Netapp's NFS performance is faster, primarily because of the huge gobs of
NVRAM that their boxes have. This is especially true when the client(s)
write to disk. When the write request is sent to the NetApp, the NetApp
immediately replies with a 'write is complete' instead of waiting for it to
write to disk. (The reason it can get away with this is because of the
NVRAM). Also, I would imagine the NetApp is highly optimized to cache data
for read performance as well as write performance...
Of course, NetApps cost a LOT of $. Well, maybe there's a few on EBAY or
something..
