How big is defaultSendBufSize?

If it's something like 1 Gig, then it's the OS that should be commended for the miracle of throughput, not Go. Even VB would be able to pull numbers like these with aggressive buffering.

A more sensible metric would be to measure the throughput and the longest time in transit. If you get Go deliver 2 mil/sec with sub-ms delivery time, then we'll have something to talk about.




I work with Derek at Apcera. The send buffer in the test is 16kb.


Yeah, how much is the buffer size?
