Sure.
As I said, I was expecting lower performance; not *this* lower, however.

 Is this normal in your experience?

 Did you do them in that order, or did you do the smb (slow) one first?

 If the slow was first, I'm thinking caching on the server could be a major 
 factor.

Yesterday I did four test:
_ SMB find resulting in over 10 minutes first time;
_ SMB find resulting in nearly 10 minutes second time;
_ NFS find resulting in a little over 1 minute first time;
_ NFS find resulting in a little less than 1 minute second time.


Today I tried again in reverse order:
_ NFS find took 3 minutes;
_ NFS find again took 21 seconds;
_ SMB find took over 9 minutes;
_ SMB find again took again over 9 minutes.

So, while caching plays a role, it just isn't it.
The server was possibly doing other things, so the above figures might 
not be that correct; however a difference in the magnitude order is just 
too big (and deterministic) to be considered random noise.
