Since I installed TFS on Windows 7 64 bit, I can't figure out why it very often hangs, with apparently no reason:

  • no evident anomaly on task manager or procexp: CPU usage rate low, a lot of free memory
  • Event Viewer is empty

Did anyone else experience this?
How can I improve the performance of the system?

Some things to try. Disable anti-virus. Reinstall TFS. Which version of TFS are you using? –  murisonc Mar 8 '11 at 0:34

I was having the same issue with TFS where it would hang and become unresponsive.

I found a solution to this by updating the tf.exe.config or devenv.exe.config file with the following configuration values.

<system.net>
    <connectionManagement>
        <add address="*" maxconnection="1000"/>
    </connectionManagement>
</system.net>

I set the limit to 1000 on my side, as i carefully watched the value in Resource Monitor, though truthfully i never got higher than 600 concurrent connections.

Fire up Process Explorer, find your hung process and try and work out what it's blocked on. It will hopefully give you some pointers to the underlying cause.

with procexp I meant Process Explorer. –  onof Mar 9 '11 at 7:52
    
If you have never used any of the Sysinternals tools before I would take a look at Mark Russinovich's webcast Case of the unexplained found here: bit.ly/hIWIM0. It has some great problem solving logic using the sysinternals tools –  jgardner04 Mar 9 '11 at 15:49
