Does wangle have official benchmark data?

I modify the telnet example to echo protocol.

I test it use my echoclient with 10 bytes playload，then the qps is only 13w。 My hardware: model name : Intel(R) Xeon(R) CPU E5-2450 v2 @ 2.50GHz cpu MHz : 2500.000 cache size : 20480 KB MemTotal: 132133772 kB OS: CentOS release 6.3 (Final) with gcc 4.8

The qps is only 13? I'm not sure I quite follow.

No, we don't have an official benchmark.

Accepts will be limited by the kernel lock limit (even with SO_REUSEPORT). For raw throughput on small frames, Proxygen gets ~20k / s, fbthrift gets upwards of 500k/s with pipelining turned up. More if you start disabling some of the stats features.

Qps is not only 13,but 130k/s, its mine fault. Accepts hasn't problem. But i use the same client with libeven,its qps can get 400k/s
