Serving a half billion requests per day with Rust + CGI

SMRTR summary

CGI performance was tested across languages on a high-powered VM. Bash performed poorly at 40 requests/second, while scripting languages like Perl, JavaScript, and Python managed 500-700 requests/second. Compiled languages excelled, with Go reaching 3,400 requests/second and Rust and C approaching 5,700 requests/second. The results show CGI can be sufficiently fast for real-world use with compiled languages, despite not being the highest performance option. The experiment highlights relative language performance in a CGI environment.
