SignalR IIS worker process does not released

Question

We have a simple signalr server and client running with the backplane enabled. When I looked in to the IIS worker process I found out in the current requests tab there is always this signalr connect is showing.

When I connect like 100 clients 100 current requests are shown in the woker process view. Shouldn't these be removed after connecting or is this the expected behavior from the signalr?

Answer 1

The threads will close or get reused by new clients, its basically a thread pool, you shouldn't need to worry about it. The only time you need worry about how many threads are open is if you only have limited cpu resources, and a low open thread limit set.
