Soap Response performance

I have a soap webservice extended from %SOAP.WebService class

Lets say i have web method and have return type of following classes (either one of them)

Class ReturnTypeA

{

 Property SelectedDoses As %XML.DataSet;

}

Class ReturnTypeB

{

 Property SelectedDoses As list Of WebServices.DataTypes.Dose;

}

Hi Bapu,

without having tested the actual performance difference of these different approaches yet. Usually in a webservice context, the serialisation itself is taking less time than the logic around it.  The requests have to go through the webserver/csp gateway and you have your connections latency and bandwidth to consider as well. 

That being said, why are you trying to use %XML.DataSet? Is your SelectDoses a %ResultSet? See  http://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?APP=1&LIBRARY=%25SYS&CLASSNAME=%25XML.DataSet
