file cache performance

I think DB cache uses flat files, also, yes. But it may use fewer to store the information -- I don't know exactly how it puts together and stores query data, since I've never played around. It's just something to look into.

And what do you mean you don't know how to compare? My point is maybe the performance benefit of using cache over the DB queries is negligible -- you compare them by using zero cache and normal DB queries, then compare it with generating / using the cache files (maybe the different types).
