The other week I was messing about in MC and did some successive runs of Benchmark and spotted a difference of around 300 in the results for the same pC.
So today I carried out some testing on both my Win and Mac PC's.
For both I opened MC31 at the Start Page, let it sit idle for 5 minutes and than ran "Benchmark", recorded the score, closed the Benchmark form/window waited 5 minutes and reran Benchmark; and did that 4 more times to give a total of 6 scores. I then closed MC, re-opened it and immediately re-ran Benchmark to give me a 7th score.
The results for windows were:- 6033, 5956, 5935, 5885, 5953, 5993 and 5997
The results for the mac were;- 7625, 7548, 7584, 7475, 7488, 7548 and 8246
I was using the latest MC 31 versions on both platforms, other than any OS and AV background tasks, MC was the only piece of software open/running and had been told not to carry out any background tasks before I ran the tests.
One other piece of information - the last time I'd run Benchmark on both PC's was under MC31.0.9 and the scores were 5898 for the Win PC and 7679 for the Mac PC .
