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. <img src="https://i.stack.imgur.com/r7Se4.png" alt="enter image description here"> 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?

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.
