I have TFS 2015 installed on one of the company's servers. I try to access TFS using web access and it is extremely slow, it takes more than 5 minutes for a page to load and sometimes even longer. If I restart the server, TFS becomes a little bit faster (a page would need only a minute or so to load), but soon it becomes slower.

The server itself is okay. The CPU and memory are not even fully utilized (~20% - ~40% is utilized).

Other applications that are installed on the server are working fine, so it's just TFS.

Any suggestions?

  • Sometimes it servers the page after a long time and sometimes it shows an error. But I forgot what was the error – user2931442 Feb 06 '17 at 14:25

    Go look at the system requirements documentation and ensure that the infrastructure meets or exceeds them. You're looking at the app tier, which is pretty lightweight. You're likely experiencing issues on the data tier. – Daniel Mann Feb 06 '17 at 20:09

  1. Log in the application tier machine to try to access the web access to see whether you can see the same behavior.

  2. Check the network connection between the application tier machine and data tier machine if you set up TFS in a multiple server configuration. You may try to turn off the firewall and anti-virus software on the machines.

  3. Clean the cache folder on the application tier, usually the folder locates in: C:\TfsData\ApplicationTier\_fileCache

  4. Check the Requirements and compatibility, to see whether your TFS set up on a appropriate environment.

  5. If the items above is not helpful. You may need to consider move your TFS to another hardware.

  • Thanks for your answer. The performance problem is visible whether I access the TFS from my PC or directly from the server. I couldn't find the TFSData folder (or a similar folder) should it be inside the installation folder? – user2931442 Feb 07 '17 at 07:31
  • You can check the cache folder in the TFS Administration Console on the application tier machine. – Cece Dong - MSFT Feb 07 '17 at 09:41
  • I checked the chache folder but I don't think it's the cause of the problem because it's very small in size (~7MB) – user2931442 Feb 07 '17 at 10:23
  • Thanks for trying to help me. Although your answer didn't help me, but I'll mark it as an answer because it contained helpful information that might be of a help to some others – user2931442 Feb 08 '17 at 06:44
  • Did you validate the speed and connectivity of the data tier? – MrHinsh - Martin Hinshelwood Feb 13 '17 at 04:25
