How fast is CF Judgers?

How long will it run a program (in C++) that its time complexity is $$$O(N)$$$ and $$$N = 10^8$$$? What about $$$N = 10^9$$$?

It depends on a lot of factors, but, as a rule of thumb, 10 ^ 8 operations are done in 1 second.

    You are wrong. Now that number is 10^9, or at least 4 * 10^8

You can easy check it by yourself. For example in such way: https://codeforces.me/contest/1702/submission/165129718

It isn't actually important what is the time complexity, but how many operations you perform.

Before you ask about judger performance, learn some faster algorithms.

Might help if you want to know "How to determine the (expected) complexity of expected solution of a problem by looking at its constraints?"
