[ Git Repo ]- Anthracite is a simple web server written in C++. It currently supports HTTP/1.0 and HTTP/1.1. - The benchmarking tools for Anthracite are written in Python. Anthracite is optimized for performance - and rivals the performance of NGINX & Apache in our testing. It uses a thread-per-connection - architecture, allowing it to process many requests in paralell. Additionally, it caches all - files that it serves in memory to ensure that added latency from disk reads do not slow down requests. - Through writing Anthracite, I have learned to use different C++ profilers as well as some general - optimization techniques for C++. + Anthracite is a web server written for Linux in C++. It currently supports both HTTP/1.0 and HTTP/1.1 and TLS. + It heavily uses a dependency injection design pattern to allow for a high degree of customization. + It currently uses an event-loop threading model and uses the epoll() system call to efficiently detect + events. Previously, it used a connection per thread model. +
++ Anthracite's HTTP request parser is able to parse roughly 27 million requests per second on my laptop, compared + to Boost's HTTP parser which parsed roughly 1 million per second.
