Is were any way to make aggregates work faster? Like some kind of indexes?

The only thing come to my mind is tmp tables && triggers && some kind of
functions (not sure, which and how).
You could certainly put a trigger on table c that inserts or updates values in
another table and then use that for lookups of sums. It wouldn't be a very
general solution (you need to know ahead of time what aggregates you want to
query), but it might satisfy your needs.
