实际中的C10k呢? [英] What about the C10k in practice?

问题描述

我刚刚测试了一个使用 Tornado 制作的小型应用程序，并且与 10k同时连接相去甚远！ 为了进行测试，我在 OpenSuse 12.2 64 bit <下使用了 Siege ./strong>，则该计算机为 i7 ，具有 8GB 结果如下:

I just tested a small application made using Tornado, and i'm far from the 10k simultanuous connections! To make the test, i've used Siege, under OpenSuse 12.2 64 bit, the machine is i7 with 8GB Here is the result:

siege -c 4000 localhost:8000

我收到此错误:

Transactions:                   2164 hits

如果我使用10k连接:

And if i use 10k connection:

siege -c 10000 localhost:8000

我得到一个错误:

[error] descriptor table full sock.c:109: Too many open files

推荐答案

检查ulimit命令的输出.您需要同时提高攻城和龙卷风网络服务器的文件描述符限制，才能完成基准测试.

Check the output from the ulimit command. You'll need to increase the file descriptor limit on both siege and the tornado webserver to finish your benchmark.
