Scaling Up Performance of Web Services by Pre-Serialization Response Analysis

Web services are the inseparable part of many scientific applications. Consider communication between two partial differential equation (PDE) solvers on different domains, such applications work by exchanging large arrays containing floating point data with high accuracy. The reliance of web services on SOAP leads to performance degradation in similar scenarios as the serialization of outgoing messages containing large arrays of doubles is a primary SOAP performance bottleneck. Various aspects of this problem are examined from the point of views including alternative formats, XML coding compression, differential serialization, differential de-serialization, etc. This paper proposes an approach which combines the idea behind differential serialization and differential de-serialization with a completely different implementation.
