-------------------------------------------
Today progress, where modern clients and HTTP/2 does show difference (java11,
jetty rewrote, okhttp pending):

Test buiding resolver against central
wagon 01:22
native 00:52

okhttp -- (did not rewrite since last time, unfair to measure)

> HTTP transport showdown
> -----------------------
>
> Key: MRESOLVER-308
> URL: https://issues.apache.org/jira/browse/MRESOLVER-308
> Project: Maven Resolver
> Issue Type: Task
> Components: Resolver
> Reporter: Tamas Cservenak
> Priority: Major
>
> For HTTP protocol resolver currently provides following transports:
> * transport-wagon that uses Maven 2.x Wagon, that among other protocols
> supports HTTP/1.1 as well
> * transport-http that uses directly Apache HttpClient 4.x supporting
> HTTP/1.1 but provides enhancements in form of "checksum strategy" (almost all
> of remote repositories emit those in headers, sparing one HTTP round-trip)
> As we saw, is very easy to outperform these as:
> * Maven Central supports HTTP/1.1 but also HTTP/2
> * HTTP/3 is on the way as well
> An experiment involving Jetty Client far outperformed both of existing
> transports, most probably due HTTP/2 support.
> So, clients we should consider:
> * Jetty Client
> * OkHTTP
> * Java 11 HttpClient
> Point is, to invest into something that (ideally) transparently supports
> HTTP/1.1 and HTTP/2, and more ideal would be if even HTTP/3 would be
> transparently supported (Jetty 12 works on that). We could then simply
> compare these implementations, count in pros and cons, and decide where we
> want to go,
