Re: [Boost-users] [asio] schedule work on all threads of a single io_service::run() pool?

I want to set up an io_service-per-thread, with each io_service having a deadline_timer to handle the heartbeat. The only other complicated bit is selecting an io_service to handle an incoming request.

Can't you just "round-robin" them?

It's a bit irksome to have to trade off the scalability to get this extra feature.

Why io_service-per-core would give worse scalability than thread-per-core?
