Hi,
With the 2.2.0 build I started to have a problem in the app.MapSignalR() which it gets stuck in creating the Performance Counters. It's hard to reproduce but I get it about 3-4 times a day.
This is the callstack:

Repro steps:
Run a website in IISExpress. Save the web.config and reload the site several times.
About 4-5 tries later of recycling the site it hangs.
I tried debugging the disassembled code and all I could see is the code jumping indefinitely between those two functions.

This looks to me like a by-product of this bug:

I'd like to have a config value to disable the creation of Performance Counters so I can avoid this problem if possible.
