People have proven countless times, that yield return is slower than list.Example: Is 'yield return' slower than "old school" return?

## Why is 2 * x * x faster than 2 * ( x * x ) in Python 3.x, for integers?

The following Python 3.x integer multiplication takes on average between 1.66s and 1.77s:if I replace 2 * x * x with 2 *(x * x), it takes between 2.04 and 2.25. How come?

## Why is 2 * x * x faster than 2 * ( x * x ) in Python?

The following Python program takes on average between 1.66s and 1.77s:if I replace 2 * x * x with 2 *(x * x), it takes between 2.04 and 2.25. How come?

## Why 2 * (i * i) is faster than 2 * i * i in Java?

The following Java program takes on average between 0.50s and 0.55s to run:If I replace 2 * (i * i) with 2 * i * i, it takes between 0.60 and 0.65s to run. How come?

## Why is python dict creation from list of tuples 3x slower than from kwargs

There are a couple of ways to construct a dictionary in python, for example:andWhen you benchmark these

## Why is F# so much slower than C#? (prime number benchmark)

I thought that F# was meant to be faster than C#, I made a probably bad benchmark tool and C# got 16239ms while F# did way worse at 49583ms. Could somebody explain why this is? I'm considering leaving F# and going back to C#. Is it possible to get the...

## For-loop efficiency: merging loops

I have always had the idea that reducing the number of iterations is the way to making programs more efficient. Since I never really confirmed that, I set out to test this.

## Simple for() loop benchmark takes the same time with any loop bound

I'm willing to write a code that makes my CPU execute some operations and see how much time does he take to solve them. I wanted to make a loop going from i=0 to i<5000 and then multiplying i by a constant number and time that. I've ended up with...
