What context switching? This started out as a question about spare processors 
sitting idle while there is work to do.

Step 1 is to decide whether this workload is CPU bound or I/O bound. I assumed 
CPU bound because of the initial question about idle processors, but now it 
sounds as though the processing is trivial so the workload may be I/O bound.

If it is I/O bound you may not need more than one thread, but maybe should be 
looking at using non-blocking I/O to manage your own prefetches.
