What kind of application are you talking about? I agree to a degree but we haven't run into performance issues with say 100k users, what traffic did you handle, what was the business case?

Again sounds like you are running some complex math heavy operation like say a weather service, national taxi service with lots of pathfinding, a global gaming platform etc?

Curious to know what exactly you are talking about here? Because normally you just outsource the "heavy stuff" to some remote API, service, etc. you can write in a hyper efficient language anyway.
