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.

It has been designed to be very scalable with low memory and CPU consumption, the perfect solution for embedded devices. Made for ARM, x86 and x64. Monkey is a lightweight and scalable Web Server. Originally made for Linux, it's also compatible with OSX. It have been designed with a strong focus on Embedded devices, therefore its scalable by nature having a low memory and CPU consumption, making it a real solution for high-end production servers too. Monkey is built and tested for different architectures such as ARM, x86 and x64. Monkey uses a hybrid mechanism composed by a fixed number of threads being each one capable to attend thousands of clients thanks to the event-driven model based in asynchronous sockets. The interaction between the scheduler and each worker thread is lock-free, avoiding race conditions and exposing a huge performance compared to other available options.
