Double caching is indeed a bad idea. That's why you have cache=off

cache= option is about write cache, right?
Here, I'm talking about read cache.
Or, does "cache=none" disable read cache as well?
cache=writethrough disables the write cache
cache=none disables host caching completely
Still, if there is free memory on host, why not use it for cache?
