Thanks Lynn,

...I have gone through the article, too much complicated to me and definitely not my stuff...

The thing is I know the function above is killing perf, but I do not know how to write something else despite my readings.

The goal is to submit some results to the dev team and show how crappy then can produce their coding when not being concerned by global performance...

If anyone can "translate" this little function, ideally not in CLR, that would be helpful 🙂
