TFS 2018 Update 2 RC. Slow perfomance in Web

Question

we have an on premises TFS 2018 Server with Update 2 RC.

The perfomance of the web is very slow. We work with kanban and scrum boards and it take a few seconds to load, furthermore, moving a task to one column to another can take a few seconds

The operating system is Windows 2016 Server. 16GB RAM, and 4 processors of 2.6ghz. It´s a virtual machine. It has been working propertly until the last month.

I have checked and changed:

The elastic search extension has been deactivated because it takes more than 5GB of memory

The antivirus has been disabled.

The processor is below 15% and the memory is around 50%

IIS Worker Process is taking 1.2GB of RAM

I have deleted the "TfsData\ApplicationTier_fileCache" with no success

We are out of ideas, any help would be really appreciated.

Thanks in advance

Answer 1

It's difficult to know what's going on there with this information, an approach to let you perform a best analysis could be the typical divide an conquer approach, in your case:

• Put the Agent in other machine.
• Install the TFS and MsSql Server in different machines, you can try a clean install of TFS using your current MsSql.

Once you did this you will:
- Have a more stable system.
- Be able to analyze which part is creating problems.
