Hi.

 

One of our customers are experiencing some weird issues regarding the performance..

They have Windows Server 2012 R2 databaseserver, running one SA16 database which is approx 10 Gb. 32 Rb RAM. Typically 18-20 connections.

The terminalserver is Windows 2008 R2. Also 32 Gb RAM. Often it´s just 7-8 users running our application.

Our application is located on a fileserver running Windows Server 2012R2, and the users run our application (PB2017) from a shortcut to the exe-file on a mapped network drive on the fileserver.

Most of the time it works great, but every now and then the users experience extreme drop in performance in our application.

One user reported that it took 4-5 seconds just to show the list in a dropdown datawindow, which is populated with data on pfc_postopen() of the form.

Other tasks can take over 5 times the amount of time compared to normal behavior.

The terminalserver is restarted every night with a fresh master image, and is just running our application and Office 2016.

When we connect to the users computer or the terminal server, we rarely see this issue.

The performance of the databaseserver is never a problem. 11/32 Gb memory used and never over 25-30% CPU usage.

 

Can this old version of Windows Server 2008 on the terminal server be the issue?

Is there anything we can monitor over time to catch the behavior and see what causes it?

 

Anyone has similar experience as this? And perhaps some leads on where to start looking?

We have to help our customers IT-supplier to get to the bottom of this.

 

Regards,
