What’s the “average” requests per second for a production web application

optimization

I have no frame of reference in terms of what's considered "fast"; I'd always wondered this but have never found a straight answer…

Best Solution

OpenStreetMap seems to have 10-20 per second

Wikipedia seems to be 30000 to 70000 per second spread over 300 servers (100 to 200 requests per second per machine, most of which is caches)

Geograph is getting 7000 images per week (1 upload per 95 seconds)
