You're missing my point. I'm trying to say the system needs to handle more than 300 messages/sec. I know there is significant traffic from those countries. I'm from one of those countries. If you had to pick a peak (and most workloads have a peak), what timezone do you think it would be? It doesn't matter what timezone as long as there's a peak. There could even be multiple peaks and that's better.
