我最近了解了 APC(我知道,我来晚了)并决定在我的开发服务器上尝试一下。我使用 ApacheBench 进行了一些基准测试,令我惊讶的是,我发现运行速度比以前慢。
我没有进行任何代码优化使用apc_fetch
或任何东西,但我的印象是操作码缓存应该对其自身产生积极影响?

这是我的 php.ini 的 APC 部分。除了将默认大小扩展到 128MB 而不是 32 之外,我将大多数内容保留为默认值。
[APC]
apc.enabled = 1
apc.enable_cli = 1
apc.ttl=3600
apc.user_ttl=3600
apc.shm_size = 128M
apc.slam_defense = 0
我做错了什么,还是我只需要使用 apc_fetch/store 才能真正从 APC 中受益?
感谢你们提供的任何见解。
