Analysis and Enhancement of Web Services Performance

Abstract

There is greater need for software components to be distributed. How do software components communicate and exchange data efficiently? Remoting technologies like COM, CORBA, RMI, and .NET Remoting address this issue, however, they lack either platform independence or tie you to specific software infrastructure. Web services, due to their use of XML, have gained popularity for their platform neutral ability to allow components to communicate. However, XML is verbose and may lead to poor performance.

In this thesis I study the performance of XML web services. I analyze the performance for different size of data exchange. I observe that sending data over XML degrades linearly as the size of the XML increases. I then explore ways to improve this performance. By using the DIME protocol, the performance is improved, however, it also results in the loss of platform neutrality. We derive further conclusions based on the analysis.
