A Comparative Analysis of HTTP/2 and HTTP/3 Web Server Performance

Containerization become a leading trend in the de-ployment of services, especially in cloud environments. There are many container-based virtualization platforms, but Docker is the most popular in the field. In this paper, we present an evaluation that includes important metrics such as requests per second, which measure the average number of requests processed during multiple runs and client scenarios. Additionally, the investigation examines the mean duration of a request and response cycle, as well as the average time required for establishing a connection, including TLS handshake. Moreover, the paper examines the web server's RAM usage under different load conditions. The paper aims to comprehensively understand web server efficiency and responsiveness under low CPU and RAM constraints for both HTTP/3 and HTTP/2 settings through metric analysis.
