Real-time content, offer and ad targeting decisions must happen quickly. When a user requests information from a web application, a processing clock starts, requiring a decision in as little as 40 msec. Delays in targeting decisions lead to delays in responding to the user. These delays can lead to user dissatisfaction and, ultimately, loss of audience and revenue.
