Came accross a Rob Howard article today linked form Jeff's blog. It's good stuff and definitely worth a read. I have always enjoyed Rob's talks at Tech-Ed and the like. His Tips and Tricks and Performance sessions have always been a highlight of the conferences to me. One of the things I would like to stress from his article is the Gzip compression. I have also tested this in implementation and found it to produce rediculous performance gains. The code comes down garbled from the compression too, which is an additional bonus.
