本人第一次用memcached作为缓存在开源平台Drupal上使用。

后台memcache statistics统计了memcached的一些数据，但是不太明白其含义，请教各位这些数据的具体含义？

<code>Uptime    v1.4.14 running 19 小时 9 分钟
PECL extension    Memcached v2.1.0
时间    星期四, 10/22/2015 - 15:15
Connections    5 open of 377,848 total
    
    
127.0.0.1:11211
Sets    0.00/s; 660,880 sets (3.03%) of 21,782,540 commands
Gets    306.17/s; 21,121,660 gets (96.97%); 19,062,527 hits (90.25%) 2,059,133 misses (9.75%)
Counters    0 increments, 0 decrements
Transferred    11.23 GB:351.96 GB (3.19% to cache)
Per-connection average    1 字节 in 55.90 gets; 31,904.58 字节 in 1.75 sets
    
    
127.0.0.1:11211
Available memory    61 MB (11.91%) of 512 MB
Evictions    407,004</code>

我的hits (90.25%)是指所有发到服务器端的请求中有90.25%的命中了吗？但是为什么打开一些页面还是很慢？其他数据都是指什么呢？

因为是使用Drupal的memcached module，都是module在控制，所以也不太清楚memcached缓存了哪些数据。

谢谢了！

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
