Hi Anna, we're running load tests on our prefect installation and have been making adjustments in terms of cpu allocation, number of replicas and cluster node scaling. Our target is to support 1000 parallel workflows, however its possible that we could run for the medium term with reduced capacity (say 500 concurrent workflows). If we're limited to 500 concurrent workflows then we'd need to be able to prioritise workflows that have been triggered by a direct user action (i.e. the user is waiting for it to complete) whereas background/batch operations could be allowed to trickle through at a slower pace
