Those are some impressive statistics!

I do have a question though, how many TFS Servers are included in these stats? I'm curious to see how much proxies reduce load on a TFS server.

Brian - Can you do a blog post sometime to discuss some of the complex configuration management scenarios that you face at Microsoft? Might be good to include in your 400-level talk at PDC too!

I know I would be interested in hearing more about Microsoft CM challenges and solutions.

Thanks!

It is one TFS server configured as a single application tier and an active-active SQLServer cluster with TFS on one node and analysis services on the other.

There are 4 or 5 proxies configured but the main one is a NLB clustered proxy with 2 servers. I don't know how much load it serves but last I checked it was in the > 100,000,000 requests per week.

Sure Ed, I'll see what I can do about that.

Any news on sharing the tool you use to generate these stats? It would be fun to run it against our instance to compare the size vs. MS.

That is really interesting, I should try to convince my superiors to set up some proxies. We are significantly smaller from what I have deduced running on a single box but do have some performance issues. It would probably help if they split up the load a little bit.

Hi Brian,

How is Rosario coming along? I am looking forward to the next release (VPC). And when is it time for a farm update again?

re: September '08 DevDiv TFS Dogfood Statistics

It's coming along well but sometimes it seems slowly. We don't have a new CTP at this time. We had planned to do a broad one this fall but there are discussions around changing plans so I can't say for sure what will happen. What I do know is that we are going to be talking about it a lot more fairly soon. We're going to be doing a bunch of demos of recent work at the PDC and will be having new hands-on labs.

I expect that every "event" from here on will see an increasing Rosario presence.

As for the farm... I've been thinking that it's getting to be time to give an update. I'll slip something in in the next month.

Thanks,

Brian

Matthew,

Whether or not setting up proxies will help depends a lot on the nature of the load you are seeing. Overall downloads are very cheap and the server can do a ton of them. Where it starts to become critical is when the rate of downloads becomes so high that the ASP.NET request queue fills up and the server starts rejecting quests. This happens somewhere north of 100 simultaneous requests.

I'd recommend using the TFSServerManager tool in the TFS Power Tools and looking on the statistics tab to understand where all of the load is coming from.

Mike, I published the tool for producing these statistics back in the December '07 Power Tools release and it has been in each release since then (although I don't think I've done any updates).

It's called TFSServerManager.exe. Download the latest Power Tools release and check it out.

Hey Brian,

Can you please briefly comment on the h/w config of TFS servers? What machine config does at and dt located? (cpu, ram, 32 vs 64-bit etc.). Also have you guys started using Windows Srv 2008 w/ SQL Srv 2008, or are they still on WS03 w/ SQL05?

Thanks

Tufan

The application tier is a 4P dual core with 16GB of RAM and the data tier is an active-active cluster of 4P qual core with 64GB of RAM and SQL engine active on one and Analysis services active on the other.

bharry — Wed, 24 Sep 2008 19:27:43 GMT

Oh, I should have read the question again :) The mid tier is 32-but and the clustered data tiers are 64-bit. The mid tier is Windows 2003 and the data tier is Windows 2008 & SQL 2005. We plan to move to SQL 2008 in the near future.

We are struggling with putting together a reasonable pre-production system for for validating changes (like upgrading to SQL 2K8).
