Apache Traffic Server vs. H2O vs. Python vs. Squid Comparison Chart

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.

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems, including Windows, and is licensed under the GNU GPL. Squid is used by hundreds of Internet Providers worldwide to provide their users with the best possible web access. Squid optimizes the data flow between client and server to improve performance and caches frequently-used content to save bandwidth. Squid can also route content requests to servers in a wide variety of ways to build cache server hierarchies that optimize network throughput. Thousands of websites around the Internet use Squid to drastically increase their content delivery. Squid can reduce your server load and improve delivery speeds to clients.
