[Samba] Long File Name vs 8.3 File Name Performance

[Michael T. Cheshire]

Howdy,
 
I was wondering if someone can answer a question for me.
 
Would the be a difference in performance in reading a 8.3 filename to
reading a long filename from a samba share from a Windows XP
Workstation?
 
Someone I know has suggested that when the filename is not 8.3, the
filename is actually queried twice in some way.
 
Is this correct?
 
Thanks in advance for your advice.
 
Michael.
