Our backend can open hundreds/thousands of DB connections per service process. Those queries take ~100ms to ~3s to run. Is that "long-running?" It seems average

Our backend can open hundreds/thousands of DB connections per service process. Those queries take ~100ms to ~3s to run. Is that "long-running?" It seems average to me — complex OLAP queries are the comparative advantage of RDBMSes like Postgres, after all. (These queries are not CRUD operations, certainly.)
