这是一个创建于 4200 天前的主题，其中的信息可能已经有所发展或是发生改变。
最近一直在忙着弄框架。现在还差模板引擎+插件系统就算完成了。但是效率总是觉得不满意，于是ab.exe测试了下。
测试项目就是让框架自己初始化好，然后SELECT * FROM table WHERE 1 LIMIT 0,1（table里面也只有一个row），最后，输出一个Hello Word。
我考虑如果不开APC不开数据库持久链接，能0.01秒内完成如上操作，那么也就OK了。但现在如上操作消耗平均0.017-0.033秒，感觉有点慢（而且跨度也太大了），好捉鸡啊。
所以我想问一下大家，你自己的框架初始化的速度是多少才算合格？好让我有一个优化的目标。感谢大家。

小项目不注重性能不用特意优化, 大项目不会不考虑opcode缓存,mysqlnd之类的扩展甚至db中间层.
而且法无定则，光一个include文件，小项目注重lazyload，避免无用文件的加载开销; 大项目为了opcode会尽量eagerload 我觉得这类优化没太大意思， pure php和symfony构建的项目除了benchmark， 自然人在公网访问能感受多少差异? |
