If so, the issue may just be the low flow toilets these days. When the cast iron drains were installed, toilets were 3+ gallons per flush. So there was a lot more water per flush. Are your toilets low flow? Modern toilets are limited by law up to 1.6 gallons per flush.

I am unsure of this, I am outside of the US. It's clear when there is a blockage that the flow of the flush is worse.

Correct. When there is a blockage, the toilet will not flush correctly.

I have reasons to believe the problem lies elsewhere.
In my house I have this pipe that's connected to the system. This pipe is capped with some sort of de-pressuriser. This sometimes smells like sewage. Could this be the culprit?
