可能是我的本子配置不行,服务器上连接数可以上1000

./pywebbench.py -c 1000 -t 10 http://172.16.0.38/test.php

1000 clients, running 10 sec, timeout setting 2.
Requests: 7387 total ,7385 susceed, average 99%.
2 fail:
timeout:1
connect refused:1
not 2xx status:0

------------------------------------- 2010.7.14更新 可以输出更多信息，svn版本7

100 clients, running 10 sec, timeout setting 2.
Requests: 1361 total ,1027 susceed, average 75%.
334 fail:
timeout:254
connect refused:80
not 2xx status:0

----------------------------- 测试需要，特别是测试缓存，逮住一个url压没什么用，所以写了一个pywebbench满足需求

#url中的id会顺序变化
pywebbench.py -c 100 -t 10 http://test.com/xx.php?id={10000,12000000}
#url中的id随机变化
pywebbench.py -c 100 -t 10 http://test.com/xx.php?id={10000,12000000#random}

实际数据

#这是pywebbench跑的数据,curl这么牛逼吗，远远把webbench落在后面。。。
$python ~/bin/pywebbench.py -c 300 -t 10 http://localhost/

300 clients, running 10 sec.
Requests: 20430 total 19318 susceed, 1112 failed.

#这是webbench跑的数据
$webbench -c 300 -t 10 http://localhost/

已知问题: python的线程貌似开不多，-c 500 开不了。。 下载: http://code-of-emptyhua.googlecode.com/svn/trunk/pywebbench.py 需要安装pycurl:sudo apt-get install python-pycurl
