c# - Minimizing WCF service client memory usage -

i'm implementing wcf service client aimed test several service methods. that's done using standard generated proxy class created add web reference (inherited system.web.services.protocols.soaphttpclientprotocol). need execute type of requests many times simultaneously see how affect server performance (something capacity testing server infrastructure). here's problem - each of responses these requests pretty large (~10-100 mb) , see few calls like

// parameterslist.count = 5 foreach(var param in parameterslist) {     var serviceresponse = servicewebreferenceproxy.executemethod(param);     // serviceresponse not saved anywhere else,     // expected gc'd after iteration } 

causes private bytes of process jump ~500 mb of memory , working set 200-300 mb. suspect running them in parallel , increasing iterations count 100-200 needed cause stackoverflow/outofmemoryexception. how can done then? i'm expecting removal of assigning service method response variable help, that's problem because need see each response's size. i'm looking sort of instant , guaranteed memory cleanup after each iteration.

refactored logic reuse existing objects as possible, gave ability run more clients. after period of time garbage collecting becomes slow performance acceptable.
