What to set ServicePointManager.DefaultConnectionLimit to

Question

ServicePointManager.DefaultConnectionLimit sets the maximum number of concurrent sessions for a Worker Role, but how can I find the best value here?

Answer 1

According to Microsoft Support, 12 * [Number of logical CPUs] is a good value.

If you're using .Net 4.5, the defaults are already set to more sensible values.

Answer 2

This is the best advise on getting the value is here on forums. Also read the knowledge base article listed.

The point is that the default of 2 will get you into trouble with connection drops.
