Performance of SOAP in Web Service Environment compared to CORBA

Web Services is one of the latest golden concepts that promise flexibility and unlimited potential for interconnection between systems of the same or different type. The communication is based on SOAP ? Simple Object Access Protocol, which is founded on XML (eXtended Markup Language). We have made experiments with SOAP in a Web Service Environment to find out the performance in response time using SOAP compared to CORBA. Unsurprisingly CORBA (Common Object Request Broker Architecture) is significantly faster but with the improvements that we implemented and an intelligent choice of XML parser the response times for SOAP was drastically lowered
