I didn't say python can handle <=1K, I was saying >=1K. I feel confident that I am orders of magnitude off the real limit you'd meet. The specifics of that aside, any unprepared application is going to buckle at a sudden mega-surge of users. The solution remains largely the same, regardless of technology: Make sure everything that can be cached is cached, scale the hardware vertically until it stops helping, optimize your code, scale horizontally until you run out of money. I imagine the DB will be the actual bottleneck, most of the time. There are other reasons to not choose python for greenfield application, but performance should rarely be one IMO.
