Hi Hajo, on my dev machine I get for static files using mpm_event on Ubuntu 16.04 Parallels image, current 2.4.x Apache with > h2load -n100000 -c100 -m10 https://test.example.org:12346/XXX with XXX being 2005 bytes: finished in 1.96s, 51060.63 req/s, 100.20MB/s 10844 bytes: finished in 2.22s, 45013.66 req/s, 467.93MB/s 10MBytes: finished in 44.07s, 226.89 req/s, 2.11GB/s (using -n10000, since I was impatient) So, you can see the difference with overheads and raw transfer speeds. Now, this is a machine from summer last year. If I run the same on a 5 year old quad core Intel, I get roughly 25k-30k req/s for small files and max ~1.4 GB/s on large file throughput. Now, is that relevant? Are your tests more relevant? That depends on how a site works? If you assume a site with 1 php that drags in 10-30 images, css and fonts, that will be one thing. If you server static resources somewhere else and serve only php, it's another. And there are lots of other factors that may become important here. So, I personally find the difference in your numbers between 2332 req/s and 2103 req/s not that relevant for the advantage to serve more than one request per process. But there might be a use case where it is super relevant. Also, if you want a client to benefit from HTTP/2, the mpm_prefork with "H2Worker 1" setting will give a client the same performance and timing as a single(!) HTTP/1.1 connection. Such a setup would cripple a modern browser. Sure, the server numbers such a requests/sec look great, but the page load times will not. Makes sense?
