go websocket rps, cpu, latency 全面测评

本来想测试四款websocket package的, 但是gobwas/ws数据太异常还是不放了. 今天测试的三个库分别是

• gorilla/websocket
• nhooyr/websocket
• lxzan/gws

测试代码地址: github

Env

WebSocket Protocol

正确性高于性能, 首先测试一下WebSocket协议. 每个包基本都是用的默认配置，为了节省时间，本项测试关闭了压缩.
可以看到，尽管 gorilla/websocket 和 nhooyr/websocket 宣称通过了所有 autobahn-testsuite 测试，但可能还需要开发者额外写一些代码.

• 命令

docker run -it --rm \
  -v ${PWD}/config:/config \
  -v ${PWD}/reports:/reports \
  crossbario/autobahn-testsuite \
  wstest -m fuzzingclient -s /config/fuzzingclient.json

• 结果
