Simple inquiry here,
=20
I have a program which takes 20 seconds with .NET from Microsoft and it
takes 28 seconds on mono (both run are made inside a Windows 2000
laptop). So it's about 30% slower to run it on mono. The code does
multiple least square fit of data points to generate an array of NURBS
curves, it also use log4net to write log information to a file and it
uses XML deserialization to load all the input data (about 2Mb worth).
So it's heavy on maths (lots a loops) with some IO tasks thrown in.=20
=20
Is this representative of the performance drop we can expect when going
from MS .NET to mono? Anyway, I was just curious. I'm also curious to
know if I'm even allowed to discuss performance comparisons.=20

May the source be with you.
