February DevDiv Dogfood Statistics

Overall, it's been a pretty uneventful month for the dogfood server.  The biggest milestone is that we are now consistently over 1,000 active users on the system.  Files & Folders are approaching the 100M mark and should hit it within the next few months for sure.

I've added a new statistic this month - Merge history.  That's how many individual file merges have been performed.  At 153 million, you can see we do quite a lot of merging :)

In the next few weeks we will be upgrading the DevDiv server to an Orcas build.  This is the first time and marks a pretty big milestone for us.  The team has been working hard over the past couple of weeks getting ready for it - testing builds, preparing upgrade scripts, doing pre-production runs, bug bashing, etc.  I'm really excited and eager to see this happen soon.

Looks like a major drop in workspaces in June (last June?) corresponding with a drop in downloads...

Interesting stats.  I think it helps to show that a major software development company can use TFS, especially scaling up/out over time.

Thanks.

The big drop in workspaces in June was when I went back and deleted over 1,000 workspaces that people weren't using any more :)  They seem to accrue over time.  People switch machines or just delete the local tree and don't tell the server or any number of other things.  I haven't done another scrub pass in a while.  Maybe this summer we'll do it again and you'll see another big drop.

Brian,

thank you for the posts on that topic.

How many files out of the mentioned 77 million were directly created by human beings?  If a file is on hundred branches, is it calculated as one file, or a hundred files?

Thank you,

(sorry, the previous comment was in the wrong window).

I don't have a really easy way to count that.  I get get an easy upper bound though.  Looking in the files table, I see 10.9 million rows.  That means at least 77 million - 10.9 million or abuot 66 million files are branched files that have never been modified in their target branch.  So, in in fact, the # of branched files is higher than that due to the fact that the file table contains a row for distinct every version of every file.

Looking at it another way, I know one of our main branches has something on the order of 2,000,000 files.  If I had to throw a dart at the wall, I'd guess the number of human modified files is on the order or 2-3 million if you don't count edits of branched files and 5-7 million if you do.

When I first started, this diagram and info was being circulated, and it was pretty darned impressive.
