memcached命中不高，是否设置有问题

服务器问题
1

这几天一直在搞seafie,一点一点给它添砖加瓦
陆续搞定了：

  1. 配置nginx反代
  2. 加ssl，使访问更安全
  3. 把运行用户由root改为普通权限用户，消除安全隐患
  4. 从sqlite迁移到mysql
  5. 配置memcached提升性能
  6. 修改邮件模板

折腾之路漫无止境，之后还要修改网站模板

好了，废话了一堆，返回正题，安装memcached之后查看状态发现命中率不高，是我配置的问题还是seafile就这样？不知大家是怎么样的情况？
命中率见下图

不知道怎么看没装面板

命中率超过80%，比我的高多了
