Question

PRA Jump Client and RDP session latency for AutoCad and other GPU-rendered use cases

Hello!
We are using PRA - jump client based connections as well as BYOT RDP (more hops). We have frequently noticed drastic lag /slowness when remote sessions are used for HD/4K video manipulation, 3D modelling other GPU-accelerated use cases. In certain cases Solidworks models don’t even show up in PRA. Bandwidth and remote computer resources are not a concern as these are purpose built workstations. Anyone else has faced similar issues ? any suggestions to improve performance

Where is the remote connection being made in relation to the appliance? ie, is the remote target on one coast and the appliance on the other? Another country?

I would think that screen scraping HD/4k is going to expect some latency, simply due to the resolution.

There are options in the access to console to render/lower the resolution to assist performance.

In the console, select File > Settings > Screen Sharing > Default Quality

Hope this helps.

@tdearman In this case the appliance, source and destination all are in geographically same region. Appliance is self-hosted in cloud with direct connection from Data Center allowing internal users and remote computers to connect over that link. We have tried lowering the resolution and other available options such as disabling recording , using BT-RDP instead of jump client. We have couple of things planned i.e. moving the appliance on-prem , 26.x upgrade (as release notes mention about performance improvements and support team has asked to do it before they can troubleshoot further). Can stun configuration help in this scenario ? I will also check with BYOT-RDP . The issue we are facing is we want to only allow PRA as Remote access tool but there are various use cases (GPU-accelerated, AutoCAD, graphics, UI/UX, Linux end points) where we see constant latency complaints and users start using tools like NoMachine which give them better performances

I have been facing the mouse lag and latency issues and had upgraded to 26.3.1 as per Beyondtrust’s recommendation today. It improves the performance to a great extend. In our environment all the jump sessions other than external RDP showed two mouse pointers and the lag was pretty obvious. But with 26.3.1 there has been great improvement

In my experience with those types of use cases, external BYOT RDP is the only option. We use it for GIS / high-res mapping applications and the built-in native bomgar jump client and desktop access console method is unusable. The screen scraping method that is used is just not ideal for this type of application. However, when we use Microsoft’s native RDP via the external BYOT RDP feature, we see much better results and it is very usable.

As a test, you should try to use native RDP from one part of your network (ideally replicated your BT PRA if possible, but as close as you can) TO the same graphics workstations you’re referring to and see what that performance is like using your applications. I am saying do not involve BT PRA at all to get a baseline. If that doesn’t work well already then adding anything else (no matter what the remote access product is), you probably can’t do what you’re trying to do. Or you have to use an entirely different approach like Teradici, Horizon, VDI built for 3D modeling, etc.

@idontwanna Thank you. I will try the BYOT-RDP option . Also as you mentioned we are evaluating alternate approach as these are special use cases which native RDP too cant support at times

May be unrelated, but we've seen similar performance issues when remoting into physical workstations with no monitor connected. Installing HDMI dummy dongles improved performance significantly.

We've also seen different results between BT Remote RDP and Jump Client console access.

In some cases, using a local Jumpoint/gateway server on the same network as the target endpoint has also improved performance.

@Darryl B Thank you for the suggestions. I have a different slowness issue reported by users on other coast. I will try RDP and BYOT-RDP with a jump point placed in that region
