--fast-io #380

Open angristan opened 5 years ago

angristan commented 5 years ago

From the man:

--fast-io (Experimental) Optimize TUN/TAP/UDP I/O writes by avoiding a call to poll/epoll/select prior to the write operation. The purpose of such a call would normally be to block until the device or socket is ready to accept the write. Such blocking is unnecessary on some platforms which don't support write blocking on UDP sockets or TUN/TAP devices. In such cases, one can optimize the event loop by avoiding the poll/epoll/select call, improving CPU efficiency by 5% to 10%. This option can only be used on non-Windows systems, when --proto udp is specified, and when --shaper is NOT specified.

Can someone confirm that it silently fails when used on Windows?
