HttpClient for load testing

[alexandrehtrb]

Hello,

Let's say a .NET program wants to use HttpClient to perform load testing and send as many requests as possible.
In this situation, is it advisable to keep using only one instance of HttpClient, as is recommended in most cases?
Which other configurations should be chosen for this scenario?

The underlying HttpMessageHandler holds the resources. While HttpClient can be recycled over the handler, usually it owns a handler and should be reused.

HttpClient and HttpMessageHandler should be reused in most situations, unless the application uses web request rarely.
