Also look at sys.dm_os_wait_stats. That's going to tell you specifically what is causing things to slow down on the server. It won't narrow it down to particular processes or anything,...

Yeah, it does sound like contention. Since it's a restore, the most likely place is IO, but it's also going to affect CPU, memory, etc. I would look at sys.dm_exec_requests...
