New techniques to develop low-latency network apps


Right click “Save as…”

Slides (view online)

For performance-critical apps, every microsecond saved means money. Windows Server 8 makes it possible to increase throughput, handle higher message rates, reduce latency and jitter, and lower CPU usage, all with standard server hardware. The new Registered I/O (RIO) model in Windows 8 delivers a low-latency solution while maintaining on-the-wire compatibility with existing TCP and UDP protocols. Additionally, a new fast path loopback allows high-speed apps to achieve a higher level of performance. Attend this session to learn how to program and tune these new capabilities and to witness them in action.

    It seems like a portion of the talk is missing when they begin to describe RIO as compared to overlayed IO.

    Thank you - we are aware of the problem and are working to fix it

    I am kind of disappointed that RIO doesn't make it possible to keep the memory usage low when there are a lot (like 10,000) of active connections. Or do you have more in store for us?

    See http://antirobotrobot.tumblr.com/post/5094268092/wsarecv for a short explanation of the problem

    The video has been fixed and is back on line.
