It can work in certain configurations. Especially if you *only* serve static files. As soon as mod_php, proxy connections or gzip/brotli content compression gets in the mix, it may get slow or stop working altogether. This is not a bug, but a principle collision between HTTP/2 parallel requests and mpm_prefork single-threaded model. In pre-2.4.26, we kept it single threaded and people experienced bad performance and locks. In 2.4.26 will had several threads and people experienced the crashes of mod_php. People that require prefork are better served with the 6 parallel connections of HTTP/1.1 clients. People who do not have to run their server single-threaded are better off with mpm_event. There is no good comfort place for h2+prefork. We think we can invest our time better in other places.
