Unfortunately I don't have any solid numbers. I can definitely tell you that it's significantly faster in production settings when compared to using '+' to build up logging strings, but it will definitely be slower in debug settings when reflection is used. My focus has been to make it as fast as possible under all settings, but to focus more on the production performance, since that's what affects end users the most. In my opinion the ability to leave verbose debugging messages including lots of well formatted data in the program for those times when bugs crop up in the field, without degrading performance for every other user of the system is a huge win.

Out of curiosity, how fast is your solution compared with the standard syntax parser? Problem with logging systems is that they have to share cpu-cycles with the main program, so they need to be fast to avoid slowing the main program down.****

I have a bit of a discussion on why a more robust formatting option is desirable. Check out http://code.google.com/p/anodyzed/wiki/Log****
and please feel free to ask any questions that come to mind.****

It would be a nice addition to have positional, but how warranted is it?** **

This avoids calling the toString() method on the objects until the log message is actually required to be logged.****
Sorry, Brett, I changed the subject without actually changing the subject since it was semi-related. :) I was asking about "{0}" versus "{}".****
