From: Marek G. on 2 Mar 2010 16:42 Hi all, I have questation about webservices and iis 7,5 on the 2008 R2 server . I have webservice which called from apl.Apl have 100 threads , but the iis w3wp process have only 30 threads . Where is trouble ? thanx
From: Patrice on 3 Mar 2010 05:45 Not sure what is "apl.Apl" but if you mean that you are simulating 100 clients calling the web service at the same time, this is perhaps not a problem. The idea is that ASP.NET allocates a number of threads and if one request ends quickly then the same thread is available and can be reused for the next request so it doesn't need 100 threads... Else clarify a bit as it is not clear where you see you have 100 threads... -- Patrice "Marek G." <grolms(a)volny.cz> a �crit dans le message de groupe de discussion : ePT4WFluKHA.5812(a)TK2MSFTNGP02.phx.gbl... > Hi all, > I have questation about webservices and iis 7,5 on the 2008 R2 server .

Does ir un in multiple threads. Does the service does a Thread.sleep to left some time for those multiple requests to be processed at the same time ? Could it be also a client side setting ? Do you check the right counter in perfmon ? Start perhaps fresh with : http://msdn.microsoft.com/en-us/library/ms979194.aspx Use really multiple instance of your browser so that each can get a distinct session (you also have a session locking mechanism so you can't run anyway two request using the same session at the same time). From there you should be sure to watch the right counter in perfmon and see if it behaves as expected.. |
