Serving a half billion requests per day with Rust and CGI

In my previous post Serving 200 million requests per day with a cgi-bin, I did some quick performance testing of CGI using a program written in Go.

Go works excellently for CGI programs, for many of the same reasons it works so well for CLI programs and system daemons.

But, out of curiosity, I decided to do a bit more CGI testing with other languages.

CGI is good technology, actually

There’s a misconception that because CGI is old or because many CGI scripts had security vulnerabilities, CGI itself is somehow insecure or bad.
