I would try with 256 first to see how it behaves, ooniprobe doesn't needs that much memory

We experienced an increase in the avg INSERT query latency during high measurement volume after scaling the ecs cluster to include more machines. This could be due to the db being a bottleneck in terms of the number of client machines in the cluster. To this end, this diff reduces the number of machines and spins up larger ones instead so the total count of machines stays low.
