This is very subjective. Using Python influences your architecture in ways you would not encounter with other languages.
I maintain a critical service written in Python and hosted in AWS and with about 40 containers it can do 1K requests/sec with good reliability. But we see issues with http libraries and systemic pressure within the service.
1k requests/sec over 40 containers, meaning 25 RPS per container. Are you using synchronous threads by any chance (meaning if you're waiting on IO or a network call you are blocked yet your CPU is actually idle)? If so you might benefit from moving to gevent and handle that load with just a handful of containers.
