Consider the situation
where the randomly fetched pages are mostly (or even entirely) cached in

RAM-cached indices.
I think fooling with effective_cache_size is a better way to model
that situation.
The default value of effective_cache_size is 4 GB. Which value should
be used instead on a system which only has 4 GB of total RAM, but still
uses RAM-cached indices?
Thank you very much for the clarification!
