Does the HttpWebRequest limit for two connections per host apply to HttpClient?

Does anyone know with certainty if the default speed limit for two connections per host applies to System.Net.Http.HttpClient.

Please indicate the source of your information and whether it is possible to increase this limit, for example, or is there a better / easier way to do this.

Also, is there a limitation? for example 40 calls per minute on top?

There is a good article on throttling tactics using Reactive Extensions here , but I was wondering if there is an HttpClient way.
