In a discussion whether to use a property or a variable, I expected that a variable would be faster than a property as it doesn't have the overhead of setters/getters so I ran a test comparing assigning a variable vs a property. Turns out that as long as no setters are involved a property is the fastest and a local variable is the slowest. Once the setter is added a property is much slower as expected. Is this a known difference ? Before this test I assumed a local variable to be the fastest of them all. Did I make a mistake in my test ? lqqqqqqqq Information qqqqqqqqqk x 106 :Local var x x 85 :global var x x 55
