but I Just need a genera idea if this is something that would increase the processing by 100 fold or not.
Short answer: no.
Having first learned to program on an 8051, I still find it jarring when confronted with languages which 'do more' being as performant as those which run closer to the metal. Micro-benchmarks can be manipulated to show almost anything of course. The only way you'll know for sure is to profile your simulation, find the 20% of code that takes 80% of the time, port it to C++ and measure again.
However, with caveats...http://unriskinsight.blogspot.co.uk/201 ... olves.html
...I doubt you'd get anywhere near a 100x speedup...http://onlinevillage.blogspot.co.uk/201 ... han-c.htmlhttps://www.dinochiesa.net/?p=920
(If you do profile, post back and let us know what the results were!)
