>> Could you post your measurements about the differences on "keep stuff in
>> RAM" vs. "access a lot of files"?
> I did not keep the profiling data from the last year where I started

> > There has to be a certain breakpoint where accessing lots of file
> > out-race the RAM usage.
> Keep in mind that PHP cannot keep anything in RAM from request to
> request. It has to be loaded upfront from disk to ram during the
> bootstrapping process and introduces its own delay. Parsing that large
> arrays and building them is expensive too. Still the issue with that is
> that the information is needed exactly just once per entry.
