Added performance tests for different (un-optimized) versions of For loops
|
| Feb 14, 2018 at 15:07 | comment | added | paul bica | fc = fc - 1 will not make a big difference, but the idea is to move all unnecessary operations outside the loop - repetition will amplify all extra operations. I’ll measure it and post the results by the end of today | |

@ThomasInzina this type of question is about the only good argument I have for Option Base 1, which I still can't bring myself to use.

Added 2 images: test results with OP code compared to test results with code in the answer

The OP's code works because he is using two complete arrays. By swapping columns individually, you are not putting the data in the right order. When i = 0 Column 9 is swapped with Column 1. Then when i = 5 Column 1 (which is the data from Column 9) is swapped with Column 6.
