Hi Bilbotine:

Yes, the link you provided gives me an idea of what needs to be done.

It’s been a couple days now since I disabled hardware decoding on the client and I haven’t noticed the sluggishness I had earlier. I’ve attached CPU usage for the client and server #1, which is the one I use most.

I think the next step will be to re-enable hardware decoding and see if the sluggishness comes back. If so, I’ll update with new CPU usage info.

Thanks.

Hi Bilbotine:

Thanks for your reply.

I’ll answer some of the questions, with a commitment to provide an update with CPU usage information soon (but maybe not today, a lot of things going on around here right now, and after a few changes described below and reboots, things are doing ok for the moment.)

NX Client:

Windows 10 Pro, 21H2 release with all updates applied

AMD Ryzen 5 Pro 4650U with Radeon graphics 2.10 GHz

16 GB RAM

Nomachine version 7.10.2

NX Server #1:

Debian 11 Bullseye fresh install (yesterday) fully updated OS and packages. XFCE4 desktop version 4.16.

Intel i3 2120 CPU @ 3.3 GHz

AMD Cedar [Radeon HD 5000/6000/7350/8350 Series] graphics @ 33 MHz clock

32 GB RAM

Updated to Nomachine version 7.10.1_1_amd64 yesterday

NX Server #2:

Debian 11 Bullseye fully updated OS and packages. XFCE4 desktop version 4.16.

Intel Core i7-3630QM @ 2.40 GHz

Intel 3rd Gen Core processor Graphics Controller

8 GB RAM

Updated to Nomachine version 7.10.1_1_amd64 yesterday

Other Information:

Both servers are connected via a Gigabit switch to a Netgear R6400 v2 router. The Windows client is connected to the servers via the router’s WiFi link (5Ghz). The wireless link is pretty lightly loaded. At the moment the Windows connection to NX server #1 is the only active link. I sometimes have a wireless link to an Amazon Fire Stick 4k and/or a Samsung Galaxy Tab 3 active on the link, but those typically don’t make much difference.

When I see the issue, it affects both of the Debian servers, which, along with the fact that the problem didn’t show up until I replaced my Laptop in February with an AMD processor based one, leads me to suspect something on the Windows end.

This morning I disabled hardware encoding on the Windows client, and rebooted. For the moment, the performance seems ok, but it sometimes takes a day or more after rebooting Windows before I start seeing the issue. Since I’ve made some changes, I’ll watch it for a while and provide CPU usage numbers if it shows up again. The Linux load averages should be easy enough to collect, but what form would you like to see the Windows numbers in? (I’m not much into Windows)

Thank you for your time.
