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.
