Of interest, it appears the random number generation is the bottleneck.
I stripped and simplified the code to the first example below, and it averages
11.5 seconds, a drop of about 5 seconds. Using brackets ie (characters 1
through 6 of temp) sped things up, (and adding a ‘my’ in front of the number
formatter caller of my old code added 2 seconds.)
I then modified the code as per the second example, and the time average did
not alter.
Any way to speed up the generation of a random number, please?
It’s also remarkable how many seconds each time can vary by! + - 2 seconds
either side of a rough average.
