 Hello,

 I've upgraded the number of thread of my fileserver to 128, and I split 
my fileserver and ptserver/vlserver.
 Now my fileserver just do fileserver and my ptserver/vlserver just do 
vlserver.
 It's a little bit faster but just on the computer who are not copying 
the file I'm using for my test, but it's looks like
 an arla isssue more than a openafs-server issue.
 Thanks a lot.
