Re: HTTP/2 support in Maven

Hi, we have done a bit more testing in a proper isolated perf environment using a Java application (added to the same repo) [1]: JDK Java HTTP/1.1: 3166.41 / 10 = 316.641 ± 64.438 ms JDK Java HTTP/2: 3008.88 / 10 = 300.888 ± 34.369 ms Apache HTTP/1.1: 10916.22 / 10 = 1091.622 ± 354.572 ms Apache

Hi Michael, I do not think it is necessary to download ALL of them serially. H2 Server push might become a big advantage as already mentioned. e.g. if requesting a pom, it might push the jar and its dependencies right away with it. THAT would probably save a lot of connections (and time). The

Re: HTTP/2 support in Maven

Yes, I think it does what you expected and it downloads the whole content of the files. :-) I did checks on the content size and it matches. Honestly, your numbers are smth I expected to get - a small performance improvement (~10%). I don't know why the difference is so high on my laptop, but

Re: HTTP/2 support in Maven

http/2 is not available before Java 8. ALPN and TLS 1.3 are requirements for h2. I saw httpClient 5 implemented http/2. That's fine and that's why you may have successfully connected tomcat with a http/2 client. Try another application server which does not use httpClient, e.g. OpenLiberty. You
