WebMethod() is slow on each execution compared to when I run it as a windows application

I have developed an application that interacts with IBM ClearQuest. The problem is that when I run everything locally, such as, run the webservice local and then ASP page local everything is at the speed I expect. When I post the webservice (precompiled) to the server and run the web page through the server, the call to the webmethod takes at least 10x the amount of time it should. I dont know why this is happening. I made a console application that has the function in question and execute it on the server and locally and they both return the same amounts of time (roughly) its just when I move to executing via the webmethod everything grinds to a snails pace. Any ideas? This happens every time not just on the first call.

WebMethod:

The code should execute in about...6 seconds.

Usually things like this boil down to problems in permissions. For example, is the web service expecting an anonymous user or is it using windows authentication. This would impact the web site as well. So I'd start looking into that.

Regardless, I would highly encourage you to post your code over at https://codereview.stackexchange.com/ You might get some feedback with regards to how better to structure what you've done.
