How many users will your Team Foundation Server support?

This is extremely good info.

One question that comes to mind, however, is how other factors affect server performance other than just the number of users.

For example, in our environment, we might see 100 people or so in a few months, but distributing that over, say, 15 different Team Projects, and not over a single one. How does that affect performance, and possibly sizing of the databases?

That kind of thing might be interesting to know :)

Size of data in any dimension can affect performance somewhat. We are trying to test the ones that we think are the "key" determining factors of performance and scale. The biggest single scale factor in number of Team Projects is the number of work item types (each Team Projects adds new ones based on the process template you choose).

The reason is that each work item type comes with a set of rules and as you create more the rules table gets bigger and adds a little overhead for workitem rule evaluation on saves. That said 15 Team Projects is not going to be significant. We have tested up to 800 Team Projects as part of our "Limits Testing" - we are shooting for a 1000 but we hit a perf bottleneck with the work item type rules (which is why I know it's the biggest effect of Team Projects :)).

I think I just figured out the topic for my next blog post. I'll write up a post on the limits testing we are doing. We're testing some VERY big data sets.

Thanks for the question,

The truth is there are many things that can affect it. Setting aside hardware configuration for a moment, the single biggest effect I've seen is the size of operations that you do. For example, in DevDiv, we do merges, checkins, branches, etc of 1 million or more files many times per day. Those are the most demanding on the system.

The number and frequency of large operations are going to depend a lot on your development methodology. We have hundreds of branches that work in isolation for months at time (sometimes) and are creating new ones, deleting old one and merging changes between them on a daily basis.

However, the simplest measurement I've been able to use is # of users. Most everything tends to vary with it - size of code base, complexity of development process, degree of isolation, etc. It's not perfect, but it's not a bad correlation.

Does anyone have experience storing large binary objcts in TFS source control? We have a stubborn wed design group that wants to store some of the website content in TFS. The content consists of thousands of images, flash videos, pdfs and mp3s anywhere from a few KBs to multiple MBs. The volume in total will be about 30GB on disk...we don't know what that will translate to in terms of growing the underlying source control database on initial check-in. My guess is that we will need to consider these (what I would call non-standard) usage practices when evaluating the capacity planning guidance laid out here due to the number of large binaries flowing into and out of the system. If anyone has a recommendation (other than don't use TFS that way) or has any experience with using TFSC in this way I would love to hear about it.

We use it for some large binaries. DivDiv uses it to store all of the tools and libraries to build VS. We also store thing like setup images for the .NET Framework redist. Some of those are a gigabyte or two.

One of our IT teams used TFS to check in all of the PPT decks from Tech Ed one time and that was about 70GB spread across a few dozen files.

Overall, it should handle it just fine. The big thing is going to be how often they change because that's where the size is really going to add up. If you check in new versions of them every week that's going to be on the order of another 30GB every week.

In TFS 2008, you can prune old versions when you need to but we don't yet have any way to configure it to automatically do so.
