Hello Raminda, I've just looked at your results (in your letter 14/07 with PDFs attached), and here is a summary: ---------+--------------+-------------+ metric | nginx-1.16.1 | nginx-quic | ---------+--------------+-------------+ | | | avg rps | 25 | 25 | max rps | 80 | 61 | | | | avg resp | 564 | 597 | 95% resp | 570 | 591 | max resp | 1550 | 1342 | | | | ---------+--------------+-------------+ | | | FCP* | 0.4 s | 0.6 s | SI | 0.8 s | 3.7 s | LCP | 0.4 s | 0.9 s | TTI | 0.5 s | 1.9 s | TBT | 0 ms | 0 ms | CLS | 0.016 | 0.015 | | | | Rx | 240.973 | 240.489 | Tx | 388.72 | 388.524 | ---------+--------------+-------------+ * First Contentful Paint, Speed Index, Largest Contentful Paint, Time To Interactive, Total Blocking Time, Cumulative Layout Shift Looking at it, I don't see any real difference, except in metrics related to rendering, like some syntetic 'Speed Index'. You may want to dive into details how your application interacts with server and find out what happens, if such results are repeatable. Maybe some difference in HTTP/3 implementation affect it, but I have no idea how this index is calculated. Also, 25 rps is really low load, unless your system is a very slow machine. What are the parameters of your machine? Finally, I'd like to know, how did you manage to get QUIC HTTP/3 support in k6.io ? I don't see it in opensource version? Is it some dev branch? _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
