   The Go program cannot be compiled.
   ‘runtime’ should be imported.
   ‘panic’ only takes one argument now.
   Moreover, now ‘;’s are not necessary.

   You used taskset -c 1-7, but in the code
   runtime.GOMAXPROCS(8); // 8 cores

   ‘panic’ only takes one argument now.
   Moreover, the ‘;’s at the end of each statement are not necessary now.

   You used taskset -c 1-7, but in the code
   “runtime.GOMAXPROCS(8); // 8 cores”
   How about chang ‘8’ to ‘7’ too?

   Great test. Interesting how well Java stands in these tests. At the level of C performance with much higher level features.

   What would really really make the picture perfect is adding the node.js hello world. (It’s on the front page of http://nodejs.org/). People talk very highly about it’s performance, but I don’t know how it would stack-up to these top speed platforms.

   It probably can’t be faster than compiled Go, and even go is relatively “bad” in this company.

   Too bad you did not include G-WAN in your test:

   http://gwan.ch/

   Not only G-WAN’s C scripts are much easier to write than the ‘modules’ of other servers, but they execute much faster.

   Here is the (10-line) source code of an hello world sample:

   http://gwan.ch/en_developers.html

   And many other samples (SQL, etc.) are there:

    I saw a test of node.js vs Erlang somewhere else, and in that test node.js had memory leak issues. For me there’s no question, Erlang is better and more reliable then node.js for high load services.

    Node.js = cancer. If you use that piece of crap for any sizable project you have much bigger problems than performance.

    I use node.js in a project with 15k lines of code. It’s mature (even though it still didn’t reach v1) and definitely fast. I think it’s one of the best things happened to web development.

    […] 此后不久看到了新浪微博架构师对netty的一个评测（原文：C, Erlang, Java and Go Web Server performance test），这个评测受到很多人关注，其中就有netty的作者 Trustin Lee。起因是这个评测最初使用mina测试，Trustin Lee看到后建议用netty，并且在测试后发现netty的性能表现果然不俗。现在想来这个测试略有些不公平，原来mina的作者也是这个人！大概顺序上先有了mina2，后来离开apache出了netty3（Jboss），所以在这个测试中netty3自然也胜券在握。 […]

    这项性能比较突显了软件设计中的关键权衡。虽然C语言在速度上表现出色，但Erlang的并发处理则展示了其韧性。Java的Netty在低负载下表现良好，但其缺乏请求解析会影响结果。Go在不同负载下的稳定结果引发了关于原始速度与构建可维护系统之间平衡的问题，这些系统能够提升开发者的生产力。在我们优化应用性能的同时，也不要忘记在其他领域确保稳健解决方案的重要性，比如提供安全和质量服务的 Windscreen Medics
