MySQL 查询缓存 Hitrate % 值代表什么?
使用 MySQL Workbench,我正在查看我运行的两台服务器的管理视图。
两台服务器具有相似的带宽
在一台服务器上只有一个站点,它的查询缓存命中率为 15%
另一台服务器有超过 100 个站点和 88 个数据库,并且查询缓存命中率为 70%
我处于中间位置了解如何最好地优化和提高这些 MySQL 服务器的性能,却找不到任何关于这些值的含义、好坏以及如何改进的信息。
(我已经搜索了很多,但我想我还没有使用正确的术语进行搜索)
Using MySQL Workbench I am looking at the Admin view for two servers I run.
Both servers have a similar bandwidth
On one server there is just one site it has a Query Cache Hit Rate of 15%
The other server has over 100 sites and 88 databases and has a Query Cache Hit Rate of 70%
I'm in the middle of learning about how best to optimise and increase the performance of these MySQL servers and can't find anything about what these values mean, what's good or bad and how they can be improved.
(I've searched a lot, but guess I haven't searched with the right terms)

从此处:
高百分比当然表明优化设置,但还需要考虑其他因素。
From here:
A high percentage certainly is an indication for an optimized setup, but there are other factors to be taken into care, too.
