Since we can target our code to a specific compiler and target the platform of our choice, I thought it would be fun to see what sort of differences in speed, it would bring up.
I did two tests. First I looped through integer values, the columns on the left and then object assignments for the column on the right. For the object assignment, I created a simple class with a string property, created the class and set the property in the loop. Interestingly there were some differences.
The object assignment is obviously a large percentage of what we do in an object oriented world. Visual Studio 2010 was a lot slower than 2008 all round, but did perform decently for .NET 4.0. However small this simple test is it shows quicker times from 2008, and it shows that 2010 suddenly improves when using .NET 4.0.
It took around 25 seconds longer to create the objects targeting the .NET Framework 3.5 using VS 2010, than VS 2008.
The test was done in Debug mode, Vista 64.
