Yeah, the question is more like:
Should I use ASIO+Threads, or just ASIO?

I'm betting your performance will be bound by disk IO, unless your
link throughput is ridiculously low.  Either way, since you're
expecting relatively few simultaneous connections, I'm not sure that
extra threads beyond what the ASIO io_service uses will buy you
anything.

But you should always benchmark to be sure.
