This kinda begs the question: should we port all backend Typescript code to Go (or Rust) to get a similar runtime performance improvement? Is Typescript generally this inefficient?
Another commenter pointed out that compilers have very different performance characteristics to games, and I'll include web servers in that too.
tsc needs to start up fast and finish fast. There's not a ton of time to benefit from JIT.
Your server on the other hand will run for how long between deployments?
