> If you are running thousands of servers and your CPU load isn't coming from a JIT'ed language like Java (JITs can emit instructions for the machine they are running on... because they compile just in time), it might very well be worth compiling CPU heavy packages (and their dependencies of course) from source targeting a modern microarchitecture level so you don't leave the benefits of modern ISAs on the table. Interesting, I wonder how this has affected language benchmarks and/or overall perception between JITed languages and native languages
