You're right. This particular algorithm has been tested and profiled. I gave 
you the numbers I have found when I have done profiling. That is why I use 
this almost everywhere I have to concatenate multiple strings together. While 
it is true you shouldn't spend too much time optimizing on your first 
iteration of writing your code, it is silly to use methods you know are 
inefficient when comparable methods that are efficient exist and are 
well-tested. It just makes more work for the second and beyond iterations.
