> This seems like some actual benchmarks that simulate real system load are needed before a conclusion can be made.

Both true and false. Typically, someone with good systems knowledge can estimate throughput from reviewing architecture / design / implementation.

There is no way you would be able to estimate throughput without doing any benchmarks.

Things like Big-O notation are part of introductory computer science classes and introductory algorithms classes.

BigO notation also applies when an algorithm is distributed and runs over a network. An algorithm that's O(n^2) will always be slower than an algorithm that's O(2n). You don't need to run benchmarks to find that out.

Big O notation tells you nothing about throughput in normal conditions. It tells you things about throughput in asymptotic conditions.

The parent poster also forgets about constant factors anyway.
