memcached数据疑问
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!
