Where is the settings for managing threads and their options

I am using Asp.net Core RC2 and I was wondering where are the settings to manage threads or application pool such as How to increase thread-pool threads on IIS 7.0 . Where they have in the Config

<configuration><system.web><applicationPool 
        maxConcurrentRequestsPerCPU="5000"
        maxConcurrentThreadsPerCPU="0" 
        requestQueueLimit="5000" /></system.web></configuration>

I would like to findout where I can find those settings so that I can start doing load testing . The person in the example above is obviously not using .Net Core however I figured that there has to be something similar. I am trying to find settings that allows me to change how many threads per cpu to run and things of that nature so that I can start performance tuning.
