测试 APC PHP
测试php编译缓存APC的效果。使用ab测试的命令是：/ab -n 1000 -c 5 http://localhost/abtest.php
开启APC:

开启APC:
用于测试的文件abtest.php含有类的引入和实例化，无数据库连接。
测试结果：
APC开启和关闭，CPU的占用率都是100%，这意味着处理能力相同。而完成的时间如下：
Time taken for tests: 11.464 seconds
Time taken for tests: 29.521 seconds
Time taken for tests: 10.361 seconds
Time taken for tests: 28.444 seconds
很明显，接近3倍。
