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

Cowboy is the ultimate server for the modern Web with support for Websocket, HTTP/2 and REST. Cowboy is a small, fast and modern HTTP server for Erlang/OTP. Cowboy aims to provide a complete modern Web stack. This includes HTTP/1.1, HTTP/2, WebSocket, server-sent events and Webmachine-based REST. Cowboy comes with functions for introspection and tracing, enabling developers to know precisely what is happening at any time. Its modular design also easily enables developers to add instrumentation. Cowboy is a high-quality project. It has a small code base, is very efficient (both in latency and memory use) and can easily be embedded in another application. Cowboy is clean Erlang code. It includes hundreds of tests and its code is fully compliant with the Dialyzer. It is also well documented and features a function reference, a user guide and numerous tutorials. Knowledge of the HTTP protocol is recommended but not required, as it will be detailed throughout the guide.

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.
