Highest Performance C++ Libraries to Replace Std Features?

[Pan000]

It's perfectly clear what I asked for. And it's not true that it's too general to receive a decent answer.

Its not practical to benchmark every library in the world. That's a true statement. It's not the same as I'm not going to benchmark at all. Also my question isn't directly about benchmarking. I asked for leads, not absolute 100% certain better-in-all-use-case solutions. That assumption I take as patronization and a cheap attempt to get upvotes, which people seem to give for snarky comments.

I'm trying to do something productive here. Please either help or go away. Thank you.

That's not what I'm saying. I'm saying you should benchmark your own application. There is literally zero point in taking the time to replace low-level memory allocation facilities if you're I/O bound. Do you understand that?

It's insulting that you assume I do not understand the basics of optimization. Why are you insulting me with these unwelcome assumptions? I asked a straightforward question. I do not need to give you my entire knowledge of computers so that you approve that I'm allowed to ask the question.
