最近要同事debug性能，不經意間發現現在Golang性能開始吊打Java了！！！感覺Go發展神速！！ 之前Go和Java基本是平手，甚至還有較大差距，請見https://www.cnblogs.com/sunsky303/p/6506663.html。借此機會對比了下，Java/Go http server最近的性能，畢竟這是后端同學最關心的問題之一！！
java 10 vs Golang1.12， Google上最快的2個http server性能PK, 壓測10次，取平均值。

QPS上 Go 43819.46吊打 Java 34822.08！！！
看來走Golang路線沒錯。 后續我有空會分析下原理。
