Web connection pool size

Hi,

I am doing load testing on web application. I have created the web test and calling this web test in load test.

Under Run Settings - > Web connection pool size value default shows the value 50.

I am using the Windows XP operation systems.

I am doing the load test in Standalone system. i am not using rig. Controller or Agents i am not using for generation load.

1. How much Web connection pool size we can give?
2. Can I increase the Web connection pool size to 100 or 200?
3. How to find the Web connection pool size for particular application? What are the parameters we have to consider before deciding Web connection pool size?

You will be limited to a connection pool of 10 becuase you are running on Windows XP. This is explain more in detail from the Web and Load Test FAQs, http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=396203&SiteID=1. Specifically the following two sections:

Q: What is the difference between Connection Pool and Connection Per User?

A: Refer to Advanced Load Testing Features of Visual Studio Team System, section “Choose the Appropriate Connection Pool Model.” For more information, see Considerations for Large Load Tests.

Q: How many simultaneous connections can a load test make?

A: Factors that limit the number of simultaneous connections the load test agent can make are

1) The operation system. With Windows XP, the maximum is 10.

2) The Web server. Some versions of Web servers (IIS) set limit on the maximum number of connections.

When the number of connection the load agent tries to make exceeds the limit, HttpError 403 will occur and be logged in the Error table in the Load Test Monitor/Analyzer.
