Hi, I did a performance test of HTTP/2 and its comparison with HTTP/1.1 and I would like to share my results with you.
I wrote a Python script [1] to download 100 artifacts in parallel using asynchronous HTTP client supporting both HTTP/1.1 and HTTP/2. I chose 100 artifacts [2] from Maven Central, which were downloaded when I did a clean build of one of my projects. All 100 artifacts were downloaded using HTTP/1.1 and also HTTP/2 and I stored the results in this file [3]. I did 10 experiments and measured its performance. In the middle I switch the order of HTTP/1.1 and HTTP/2 requests to avoid a possible bias. I run it from my laptop connected to 160 Mbit/s network. The experiments showed massive performance improvements when using HTTP/2 instead of HTTP/1.1 *:* - *The average download time using HTTP/1.1 was 3753.7 ms and using HTTP/2 971.8 ms* [4] - *In average the artifacts were downloaded 3.86 times faster using HTTP/2 than using HTTP/1.1* [5] Kuba [1]: https://github.com/jbartece/http2performance/blob/main/http2PerfTest.py [2]: https://github.com/jbartece/http2performance/blob/main/centralUrls.txt [3]: https://github.com/jbartece/http2performance/blob/main/testResults.txt [4]: https://github.com/jbartece/http2performance/blob/main/finalResults.txt#L26 [5]: https://github.com/jbartece/http2performance/blob/main/finalResults.txt#L32 On Tue, Oct 27, 2020 at 8:42 AM Jakub Bartecek <jbart...@redhat.com> wrote: > I'll do some measurements and share the results with you.
