how much more memcache memory do i need to get 95% hit ratio? [on hold]
- by OneSolitaryNoob
I have a memcache instance running that has a 90% hit ratio.
How can I estimate how much more memory it needs to get to a 95% hit ratio?
edit:
This question was blocked, but I do not think this is impossible
to answer. After all, anyone that's used a caching system HAS answered this
question, most likely with trial&error&luck.
I can look at my usage patterns.
I can increase or decrease memory and see how hit rate changes.
Both of these provide data that informs an estimate. But what's
a good/better/best way to do this?
