Little addition on my rant about the enter and leave instructions being better than push mov sub for stackframes:

I had that debate with a friend of mine, who tried the same code ... and failed to get enter to be as fast. Infact, for him, enter was twice as slow, on his older computer even 3times as slow.

Mhh... pretty bad. basically blows up my whole point.

I tried the code on my computer... Can't reproduce the error.

Weird.

"Which CPU are you on?"
>"I'm on Intel"

Both of his computers are on intel. I use an amd ryzeni1600. Now this might be a bit of a fast conclusion, but I think that its safe to say that intel should atleast do better for SOME parts of their CPUs.
