The evolution of Internet is heading towards a new generation of social networking services that are characterized by novel access patterns determined by social interactions among the users and by a growing amount of multimedia content involved in each user interaction. The impact of these novel services on the underlying Web infrastructures is significantly different from traditionalWeb-based services and has not yet been widely studied. This paper presents a scalability and bottleneck analysis of a Web system supporting social networking services for different scenarios of user interaction patterns, amount of multimedia content and network characteristics. Our study demonstrates that for some social networking services the user interaction patterns may play a fundamental role in the definition of the bottleneck resource and must be considered in the design of systems supporting novel applications.
