Attended CMG 2006. It was really good ! I am too lazy to write down everything that was there, but there are others: here is one detailed blog. Of course, it is just one view: there was up to 12 different tracks at each timeslot. Unfortunately papers are available to members only, but Measure IT newletter is free (requires free registration). A must to subscribe for anybody interested in performance. CMG 2007 will be held December 2nd through 7th in San Diego, California, see call for paper and for workshop.
