It depends on what you do in your IoHandler implementation. If it's
pure CPU logic, then you don't need an ExecutorFilter.

They are different from each other. Are you sure you read the thread
model tutorial? One connector (or one acceptor) takes one connector
(or one acceptor) thread, so creating 100 connectors will create 100
connector threads + 100 (or more) I/O worker threads. I'd recommend
you to create only one connector and reuse it if all connections are
categorized to the same service category; an IoService is essentially
a logical grouping of sessions with the same IoHandler.
