Case Study: BlogTalkRadio achieves faster ad serving and increased ad revenue with ScaleArc

BlogTalkRadio Selects ScaleArc to Increase Performance of its Ad Serving Application

BlogTalkRadio, the world’s largest social radio network with millions of listeners and roughly 18 million unique visitors per month, depends on ad serving to monetize more than 175 million impressions monthly. Rapid growth exposed SQL Server bottlenecks and intermittent networking issues that degraded ad‑server performance and threatened revenue as the company migrated parts of its infrastructure to Amazon EC2.

BlogTalkRadio deployed ScaleArc for SQL Server—initially by changing the SQL host in connection strings and later as an EC2 AMI—to provide transparent caching and database load balancing. The solution delivered 60–80% cache rates on heavy result sets, reduced CPU and I/O, sped ad delivery, increased ad-serving capacity and revenue, and gave real‑time SQL analytics that eased cloud database adoption.
