How many ads can I serve each month?

It is difficult to estimate the performance of a typical ad server because it depends on so many factors.

Serving 10 million ads each month
A typical web server should be capable of serving 10 million impressions a month comfortably. If you are using a shared host this may limit what you are able to serve.

Serving 100 million ads each month
We know that many publishers serve over 100 million impressions a month using a dedicated web server and separate database server.

Serving billions of ads each month
To serve billions of impressions each month using typical server hardware requires sharing the ad serving load across several servers. OpenX has a feature called distributed statistics to help administer this.

You may well find that your ad server has more or less capacity based on your hardware, configuration and ad serving requirements. We encourage administrators to load test their their ad server to find their maximum capacity.
