Hi, No, the first message says it works with 6k requests, of which 350 are concurrent, and doesn't work with 10k requests, of which 350 are concurrent. I merely made some back-of-the-napkin calculation with some very crude assumptions that 350 concurrent requests means you have a total of 100k use

350 concurrent requests for a single machine is really much. If your app is very fast (e.g. by caching stuff a lot) it might be possible, but again it might require some tuning (for example, you could increase the gunicorn workers, but you need to be monitoring RAM consumption). Do you really need

Hello, 502 usually means the backend isn't running. After you finish the test, has the backend stopped running? Does it continue to throw 502s? If that is the case, I'm wildly guessing that processes might be growing and growing in memory and being eventually killed, but I don't really know. Do yo
