Thank you. I want to make sure I understood it clearly... I mostly use Java, and my impression is JIT inside JVM introduces hardware specific optimization without any user intervention. But for C/C++ if dependency is included as source - I can use compiler flag to enable platform specific optimizations. But if the dependency was included in the form of a pre-compiled binary, such as a .dll or .so, I am probably not using the the most optimally compiled version of the dependency. Am I right so far?
