This patch is a good start, but this is a fairly serious issue.
Asynchronous IO is at the heart of high performance, scalable, network
servers. Is anyone planning on integrating asynchronous sockets with IO
Completion Ports (on Windows) and whatever the equivalent is on the
other platforms? There has to be a faster way with some kernel level
asynchronous APIs, rather than playing in user space.
Of course, maybe I just misunderstood this thread. I haven't actually
looked at the code that does this work.
