April '08 DevDiv TFS Dogfood Statistics
Due to my sabbatical, I missed the March Dogfood statistics. In my absence, adoption has continued apace. The team has been very busy making sure the server is behaving well and applying fixes when it is not.
Looking at the graphs below, you can see that several of the statistics have really started to grow at dramatically higher rates in recent months - File downloads, Files, Workspaces. In fact, the only reason you see file downloads decreasing is that we continue to move more high load users (like the build lab, checkin validation, etc) to use proxies for downloads rather than the main server.
We continue to drive improvements to handle the additional load. Unfortunately, we've had to cut off their incorporation into TFS 2008 SP1. Many many of the improvements made it, but at some point we had to draw a line and we did that a month or two ago. The additional improvements will, of course, make it into the following TFS release. However, I believe you'll find (if you also have a very large server) that the improvements that we've included in SP1 will result in some very nice performance improvements for you.
Here are the detailed numbers. If you look at them closely, you will find that they don't match the difference between what I reported last time and this time. That's because (although I didn't report it), I actually did take a snapshot a month or so ago and these differences are against that snapshot.
