I don't have that much Perl experience, but I was positively impressed with Python CGI scripts. And with statically linked things like C/C++/Go. Haven't tried Rust in production yet. Plus I still use one service in production which was written in C++ in 2009. It's statically linked and as such the binary survived 3 major OS upgrades unmodified. Around 2015 I put it behind Nginx just to be sure with all the OpenSSL issues being discovered. It was designed to be multi-threaded to fully take advantage of a dual-core Athlon with 2GB RAM. Oh wow is that one blazing fast on today's hardware.
