I sent over than 100 requests to web service I am using Parallel.Foreach and it handle it well, but when see the traffic using Wireshark I only see 4 or up to 10 requests per second.

This is not a parallel.foreach issue - the issue is ServicePointManager which throttles the number of parallel requests to any domain name. The standard is, as you found out, 4 parallel requests.

Parallel.ForEach will quue all the tasks, but then the requests run into the limitation. Oh, and that manager can be configured ;)
