At that point you're waiting for the network I/O, so there's still that
(which is sometimes actually a bit slower).  Plus, the VM's devices will
still be loaded from the compute node itself, unless it's a completely
diskless server (which has its own potential problems).  So you still have
some load to consider.  Add that to the amount of other operations
happening at the same time (file locking/unlocking, waiting for files to be
unlocked, virtual hardware initialization, resource allocation, etc) and
starting a VM is computationally expensive, even with 48 cores.
