小测试apache与nginx请求速度的对比

今天用apache的小工具ab测试apache及nginx两个webserver的响应速度。平时总能在网上看到nginx比apache如何如何强的帖子，但自己从来没有测试过。今天有空测试了一下。相同的代码、相同网络状况相同的数据库。对比情况如下：
apache：Document Length: 3960 bytes
Concurrency Level: 10Time taken for tests: 0.604543 secondsComplete requests: 10Failed requests: 0Write errors: 0Total transferred: 42400 bytesHTML transferred: 39600 bytesRequests per second: 16.54 [#/sec] (mean)Time per request: 604.543 [ms] (mean)Time per request: 60.454 [ms] (mean, across all concurrent requests)Transfer rate: 67.82 [Kbytes/sec] received

apache：最长响应的时间――604ms 每秒事务数――16.54 [#/sec] 平均事务响应时间――604.543 [ms] nginx：最长响应的时间――103ms 每秒事务数――95.91 [#/sec] 平均事务响应时间――104.265 [ms]
想到过nginx比apache强，但是都是别人说的自己是头一回亲眼见证，这大大的增强了我更换webserver的决心。至于有人说：apache比起nginx相对安全与稳定就如上面的说法一样，我也是听别人说的。回头自己亲自测试一下。实践方能出真知！

测试命令：ab -n 10 -c 10 http://www.microsoft.com/ -n:发请求次数-c:每次发请求的数量（并发concurrency ）
