I cannot follow your reasoning why you think that I don't think, and what convinced you that I have no idea what I'm taking about.
Wasn't it you who made some vague performance statement/recommendation without presenting any numbers or details on the tests one might assume you have made before writing?
I also don't see why I should read your code just because you made some statements I cannot follow.
Finally, I (and probably others as well) would prefer not seeing this type of reply, because it doesn't help anybody, ... (the rest censored by myself)...
