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。
