Ah. The answer to that is a lot more murky, since in an actual C/C++ program you're going to have a mix of local, static, and dynamic linking. You're generally not putting super chatty stuff across a dynamic linkage, since that tends to be where the stable API boundaries go. Anything internal is then going to be static linkage, so comparable to luajit, or inlined (either by the compiler initially or with something like LTO) and then even faster than luajit
