Abstract:
Web services marked a remarkable milestone in the field of distributed computing. Its
predecessors like, Java RMI and .NET Remoting had their own ways of
communication and optimized to suit their individual frameworks The gain was in
performance - which led web services to be behind. SOAP message serializing
process itself contributes 90% of the performance bottlenecks found in web service
communication (II).//
The research focuses on improving SOAP message serialization process with
Templating and Caching. With Tern plating, we use a given WSDL to generate SOAP
message templates at the time of code generation and in runtime the generated
templates will he substituted with input arguments to the web service APIs. These
substituted templates will be cached in the SOAP message template repository, with a
unique key to identify- each web service request. Cached SOAP message requests will
be used in subsequent web service calls, if a match found.//
With the performance test results obtained, we could witness that Templating &
Caching improves the web service performance and the factor of improvement
depends on the complexity of objects involved in the web service API call. Also the
performance gain due lo Templating & Caching increases as the object complexity
increases and Templating itself contributes in a larger percentage to the performance
gain than the Caching, as the object complexity increases
