Pretty charitable to call Salesforce a bastion of "efficient code" hahaha
You're lucky to be able to control as much of the stack as you want with your one "tooling" language to rule them all so that performance matters again. Although in all fairness, given the regulatory and workplace culture as well as constrained budgets, sometimes you do have to let go of chasing performance in the name of making things easier for the maintainers at work. As I mentioned in a different post, it also helps to be working in a captive market, which helps relieve the pressure a bit.
Also, my Python ETL scripts do calculations for certain things, but attempting to speed that part up with a low level language like C or Rust doesn't really move the needle for total processing time when you have latencies measured in the hundreds of milliseconds per page of data. Scale that up to multiple pages and the whole runtime is dominated by how long it takes for packets to move from my Windows Server to Salesforce and back. It's basically a whole lot of effort for very little gain.
