HttpClient vs RestSharp Benchmark

[ngoquoctoandev]

I reused the following code for a simple review. https://github.com/CodeMazeBlog/CodeMazeGuides/tree/main/dotnet-client-libraries/HttpClientVsRestSharp/HttpClientVsRestSharp
The source code in the review I have upgraded all packages to the latest version, .NET 7, hardware information as attached image below.

My performance analysis shows that both libraries are similar in time performance. However, HttpClient performs better regarding memory allocation. Is there a way to make this library even better while keeping the same performance as HttpClient.

You can't do the same as RestSharp calls HttpClient. It will always be more allocations and more time.

It's also not clear what you are comparing, there's no code to look at. It's also unclear what are you calling, what are the payload sizes, etc.

Please, if you want to suggest performance improvements, be more specific.
