The 'inline' directive instructs the compiler (or is it the linker? 😬) to try copying the whole function inline, also avoiding the call (stack) setup; you can't do this for this for a general purpose method. I'm curious how you got that 6% figure, it seems rather large. Is this comparing the parameter vs virtual method approach or comparing a fully inline (no indirect call of any kind) sort function to some other option? Are you passing the variables by reference?
