Abstract

Web servers need to be protected from overload, since server overload can lead to low server throughput and high response times experienced by client. Most architectures for overload protection have been developed for the Apache web server. Event-driven web servers handle many more simultaneous connections than the Apache server. Thus, they exhibit a different behaviour during server overload. In this paper, we study the behaviour of event-driven servers during overload. We show that an overload protection architecture that we developed earlier successfully protects event-driven web servers from overload.
