Currently each
Socket
instance is creating a newAIOHelper
object on each async operation.This PR modifies
AIOHelper
to allow it to be created once atSocket
instantiation and is reused per async operation.The
AIOHelper
class creates a pair ofnng_aio
contexts (one forsend
, and one forrecv
), so there can be only one pending AIO operation per direction - I think this is ok, but would like feedback on this.
