The main thing to look at is the network traffic between client and
Samba server - ie. does the wait occur on the client when preparing
the job or in the network traffic between client and server or at
the server end once the job has been received at the server ?

This is the first step you need to take in debugging a problem like
this. The Samba server submits the job to the backend once it receives
the EndJob RPC call.
