OK this is not my level of stack for over a decade now, but writing a multithreaded code that will generate the same pagefaults on a shared mmap buffer, as opposed to something that kernel io scheduler will do on your behalf, and presumably try to schedule optimally for your machine/workload - does not sound comparable.

Thats like arguing python is not slower than C++ because you could technically write a specialized AOT compiler for your python code that would generate equivalent assembly so in the end it is the same ?
