RDP sessions slowing down after upgradig from Win10 1809 to Win10 1909

Question

My organization recently upgraded all our Windows 10 PC's from running Enterprise 1809 to Enterprise 1909 using the MS In-place upgrade process.

Among the 150 or so units were 35 PC's hosting RDP remote workers. Of the 35 users, all but one are running conventional enterprise-class host desktop PCS...mostly HP but some Dell Intel i5's (6th to 9th generation), 8GB RAM and the on-board Intel video stage. One unit however is an HP Z-station with the following specs:

HP Z4 G4 Workstation - 1 x Intel Xeon Hexa-core (6 Core) W-2133 3.60 GHz - 16 GB DDR4 SDRAM RAM - 2 TB HDD - 512 GB SSD - Mini-tower - Black - Windows 10 Pro 64-bitNVIDIA Quadro P4000 8 GB Graphics

For just this one workstation, after the In-place upgrade the end-user, also using an HP Z-Book workstation laptop, found that after 15-30 minutes that he was experiencing long lag-times. After 30-60 minutes the connection became essentially unusable and he would have to perform restarts. After some experimentation we have found that by setting the screen-saver on the host workstation to higher values that it increases how long the user can effectively work, from 15-30 minutes to around 2-3 hours. The power profile for the unit is High-Performance, and as the PC is at this time only being used via RDP, and therefore the local monitor should not be being engaged anyway, what could be causing this behavior?

Thank you for any input.

Hi

There is a know issue that can make the remote session really slow. It’s related to the mouse pooling rate from the pc where the connection come from.

I dont know if it’s your case, but it’s worth checking.

To explain the bug; It’s on the user computer, if he has a mouse like a gaming’s one, any rate over 500 make the remote session act poorly. Return the pooling rate to the default of 125 in the mouse driver to fix the issue if it’s your issue there.

Thanks

Do we have any solutions for this? It looks like this is related to "Turn off the screen after ... minutes". If I set "Turn off the screen after 30 minutes", it will be slow after 30 minutes, if I set "Turn off the screen after 5 minutes", it will be slow after 5 minutes. However, the company's policy restricted me from editing this value and I always needed to restart the remote session multiple times in one day.
