Impressive numbers for sure! While these are not as impressive, the last place I worked at was serving about 2.5-3 million CF requests per day. That averages about 104,166 to 125,000 per hour. But don't forget to remember that traffic was almost non-exstent from 2am to 5am and the peak was midday. So during he peek, there was far more than 125,000 requests.
This was done with 4 CF8 Ent servers behind a load balancer. The question is not "CAN ColdFusion scale?", but "How HIGH can ColdFusion scale?" Spread the word, ColdFusion is ENTERPRISE CLASS! High Availability, High Load, High Traffic with ColdFusion is easily doable as long as you do it right. Anyone can write an app in any language that fails under load.
