Hi,

I've seen the stats page many times, of quite a few installations and even 
more servers. There's one issue that keeps bothering me: the cumulative hit 
ratio of the query result cache, it's almost never higher than 50%.

What are your stats? How do you deal with it?

In some cases i have to disable it because of the high warming penalty i get 
in a frequently changing index. This penalty is worse than the very little 
performance gain i get. Different users accidentally using the same query or a 
single user that's actually browsing the result set only happens very 
occasionally. And if i wanted the hit ratio to climb i'd have to increase the 
cache size and warming size to absurd values, only then i might just reach 
about 60% hit ratio.

Cheers,
