In that case the only thing you can do is 'slice' the query into smaller
parts (representing subtrees of the plan), and analyze those first. Look
for misestimates (significant differences between estimated and actual
row counts, and very expensive parts).
We can't do that, because we don't have your data or queries, and
without the explain analyze it's difficult to give advices.
