[...] 已经很好的做了一个关于C（nginx）、Erlang、Java 和 Go 的测试：http://timyang.net/programming/c-erlang-java-performance/ 测试很完整，不过后面的 comments [...]

maybe these files can help scale the GO language performance, but i know fea about the GO, so i am not sure.

why not compare a pure cpp project called ‘poco’ too, it also provide a net framework and http server sample as http://pocoproject.org/wiki/index.php/Tutorialftpclient

To Tim:

May be. Sorry, I haven’t checked the source code.

But still not sure in this type of tests. I mean, I can’t see how useful they can be for someone who wants to create next Google. Very different languages can give you success: Facebook chat uses Erlang, Twitter was using Ruby, StackOverflow is written in C#, Google is using Python, eBay uses Java, …

To D:
Every http connection in this test has its own session, the program maintains all sessions and concurrent logic, not just “Socket performance”, after adding a little session state or logic code, it will become a real business server.

if you compare these results with a Ruby/PHP… there will be different, and if your own server need to handle 5,000+ concurrent connection, this test may informative for you.

What you are testing? Socket performance? It’s roughly the same.

There is no point in such type of tests. Write normal dynamic application (just wondering how you’ll do it with pure nginx ) and compare everything – development time, support, load, …

All languages will be very close printing “Hello, World”:
printf(“Hello, World”);
print “Hello, World”
or
Console.WriteLine(“Hello, World”);

on erlanh -h 99999 seems overkill. A far lower value can is better as every process does very little porcessing so no much heap is used.

You hit GC when the process dies son you are GCing 99999 that a lot of memory and is mainly unused.

Try normal setup o a very low value as a 512 or 1024.

Thanks for the update and the number looks pretty nice!

By the way, in “3. Notes”, “* Java runs better on small connections, but the code in this test doesn’t parse the HTTP request header.” now seems invalid? Also, I would replace the MINA source code from the page with the full Netty code since the test result has been replaced.
