I have a box which is approaching a quarter million hits per day. That means an average of 3 hits per second on a daily basis. The response time of the site is still almost immediate and we can increase the load by much more.

The average number of SQL hits per hit is about 20 to 25. We have about 5 million hits to SQL Server on a daily basis.

I think I remember a few years ago someone who mentioned that over 200,000 hits, there isn't much server configuration that would be able to handle much. Then would be the time to start DNS server routing for IIS and so on.

I am pretty confident that I can reach half a million hits per day on the same server without having to start spreading it.

Any of you would like to share your metrix for comparism as this would be valuable information to collect?
