見証FREEBSD和LINUX高負載效能之爭﹗請大家進來看看~~

我給出一個APACHE效能的測試語句﹐請大家自己去測試一下你的寶貝機器的運行效能﹐并把結果貼出來﹐以便大家做比較﹐謝謝了~~

測試命令一般使用ab來做的﹐它是位于安裝目錄的sbin里面﹐比如apache/sbin﹐進入之后再運行如下命令﹕

./ab -n 10000 -c 1000 localhost/

先說了來﹐按回車之前﹐最好想清楚一點﹐你的SERVER如果不穩定﹐最好不要做了﹐要不然出了事情不要找我﹗反正我的FREEBSD是做過几十萬負載測試的﹐是沒有問題的。但你的機器是否要這么做﹐先想清楚吧~~
我解釋一下這兩個參數的作用﹗
-n 10000    進行一萬次的連接
-c 1000      同時對localhost/缺省網頁發起連接數量為1000個

完整的解釋就是 向本地SERVER的一個網頁（默認網頁）同時發起1000個連接﹐共進行一萬次連接測試~~
你可以從1000﹐50﹐慢慢加上去﹐免得把系統弄死機了﹐找我的麻煩~~

怎么樣﹖怕了嗎﹖怕了請從這里出去﹗

呵呵~~﹐大家可以把測試結果跟貼寫出來﹐不過要寫清楚你帶的參數和結果呀~~

我想更正一下楼主的说法，就是用ab是不会引起系统不稳定的,它只是在可能的范围内进行模仿,而并不是真实的进行测试,所以无论你用再大的量也不会对系统有任何的影响.
不信你看看编译前ab的源代码就知道了,它只是用几个线程几行测试并进行估算,而并非全部用过去的.

所以你完全可以放心用最大的连接数和同时连接量进行测试,而不必担心是否会影响系统.

谢谢楼上的说穿这一点！
我是“害人之心不可有”呀，;)

不同意哦 ab源码我没看过 但如果-n 1000确实会产生1000个请求(可以用程序做计数) 如完成时间在50秒 则每秒的请求数在20个 这样的频率访问调用数据库的页面 很容易就too many connections或lock table的..

程序是否要调用数据库，要看你给它测试读取的是哪个网页哦…
而我测试的，最大的一个是phpinfo.php这个，系统很慢的，但我如果调用了一个html的静态网页，速度到非常好…
如果我给它测试一个含有一条query语句的mysql调用，不知道结果会是怎么样？我可以测试一下…

我的破机器.连接数到100就APACHE报错了....

我的apache2每次都是，无论填多少都是那样啊
