Return back BeginSend/EndSend to HttpClient for best performance

[okarpov]

As Microsoft mentiones Begin/End pattern more performant than Async/await

So i do suggest to return back Begin/End putterns especially for Send methods to get best performance in applications which do extensive sends.

Where does "Microsoft mention" that? It is inaccurate and we're not going to add new such begin/end methods.

[okarpov]

so Microsoft mentioned that Begin/End has performance benefits, but you said it is obsolet and wrold has changed.
You confirmed that RAM consuming is less with async/await pattern than the any other pattern.
So my final question is: does performance of the asyn/await also higher than any other pattern?

[stephentoub]

The {Value}Task-based APIs along with async/await offer the best performance and usability in general.

[okarpov]

you mean Task<value> only but not Task<object>?

[stephentoub]

No, I mean APIs returning Task, Task<T>, ValueTask, and ValueTask<T>.

Again, I'd recommend you read the article I linked.
