ABSTRACT
The performance of Web servers and application servers is a crucial factor for the success of the underlying business activity. Current commercial servers (such as Apache and Microsoft’s IIS) usually employ a thread-based concurrency policy for executing request simultaneously. However, with this policy the throughput tends to collapse when massive overload occurs. Event-based concurrency has been proposed as an alternative, but-–similar to the thread-based approach–-it suffers in its pure form from a potential memory access bottleneck. This is avoided by a server based on a Staged Event-Driven Architecture (SEDA) which combines the two approaches to take advantage of locality in data and code within each state.
