H2O
H2O is a new generation HTTP server that provides a quicker response to users with less CPU utilization when compared to older generation of web servers. Designed from the ground up, the server takes full advantage of HTTP/2 features including prioritized content serving and server push, promising an outstanding experience to the visitors of your website. Full support for dependency and weight-based prioritization with server-side tweaks. Thanks to others, H2O is provided as a binary package on some environments. Therefore you may try to at first install the software using your favorite packaging system, and then resort to installing from source. Generally speaking, we believe that using LibreSSL is a better choice for running H2O, since LibreSSL not only is considered to be more secure than OpenSSL but also provides support for new ciphersuites.
