Well, I'm behind a couple of blog posts already.  I'll do this and get to the one on Team Project organization tonight or tomorrow.

We've been finalizing the limits that we are going to test TFS to for its release.  I wanted to share them so you know how far we are pushing the system and can use that information as one of many factors to decide if TFS will work for your organization.  First a few notes on methodology and scope.

This testing is primarily focused around the "capacity" of the system.  Generally for each thing that TFS can store or manipulate we must ask "how many" and "how big".  While the list you'll find below does not include every single datum that can be stored, it includes the majority and particularly the ones where we want to ensure the capacity is very large.  Many of our other "limits" (like length of a file path, for example) are covered elsewhere in our functional testing and are not called out here.

For each item, you'll see a "requirement" and a "stretch goal".  The requirement is the capacity we must achieve in order to ship.  The stretch goal is the capacity to which we will actually measure.  Anything over the requirement is considered good enough.  Anything at the stretch goal can probably go higher but we aren't going to measure any higher.

You'll also see a "count" and a "size".  It's not always obvious how to interpret these.  Generally counts are "how many" - like how many files can the system have or how many work items.  Size can get a bit wierd because sometimes it is also measured as a count.  For example: Workspaces - count means how many workspaces can be stored on the server; size - means how big can a workspace be (measured as the number of files/folders mapped in the workspace).  I don't think we've been exactly consistent in how we use them but I've tried to clarify with text.  For some items we haven't included both count and size if we felt having both didn't make much sense.

Generally this only includes the counts and sizes of things and doesn't talk about operations.  We will be testing operations on the counts and sizes to make sure that the system is really working with that much data in it.  We have called out a few specific operations that we were particularly interested in.

Lastly all of this refers to the data that can be stored in one server.  Many (especially larger) organizations will setup multiple servers.  And for the disclaimer - all information is subject to change without notification :)

As always, we're interested in any feedback or comments that you have...
