我最近了解APC(我知道,我来晚的演出),并决定尝试一下我的开发服务器上。我做了一些基准测试与ApacheBench,让我吃惊,我发现,事情正在运行慢比以前。APC让PHP 5.3更慢?
我还没有做任何代码优化使用apc_fetch
或任何东西,但我觉得操作码缓存应该对它自己产生积极的影响吗?

这是我的php.ini中的APC部分。我最左边的东西在默认情况下,除了不断扩大的默认大小为128MB,而不是32
[APC]
apc.enabled = 1
apc.enable_cli = 1
apc.ttl=3600
apc.user_ttl=3600
apc.shm_size = 128M
apc.slam_defense = 0
难道我做错了什么,或者我只需要使用apc_fetch /存储真正得到好处APC?
感谢你们能给任何见解。
_“注意:在Windows上,APC需要一个临时路径来存在,并且可以通过Web服务器写入,它按顺序检查TMP,TEMP和USERPROFILE环境变量”_此路径是否存在? – Wrikken 2013-03-11 16:54:48
APC应该有所作为......你有AB数字之前和之后,还是之后? – 2013-03-11 16:55:28
而且要知道,有很多其他因素的影响,如不良的数据库查询或文件访问可以有一个很大的不利开销 – 2013-03-11 17:12:36
