You're saying that it is taken for granted that ASIO is bad at handling a
great deal of (small) tasks? Taken that for true, then asio also must be
bad at handling a large number of small network messages. I.e., I shouldn't
try handling all data of a couple of NICs with ASIO, at least not using a
threadpool setup?

I was under the impression that ASIO is a high-performance asynchronous
event and IO library, and as such, is good at everything it does... Perhaps
a lock-free task-queue would change things for the better.

Thanks for pointing out TBB, I'll take a look -- however I'm primarily
interested in taking message handling/event handling to the max.
