It could work, after lots of testing, I think the noise papagno is experiencing is mostly caused by the servo thread spiking above 1ms, so widening the cycle time could certainly help.
The main reason why Debian 10 does not grind in his case, is mostly because Debian 10 with kernel 4.19 gets lower latency, and this is pretty universal IMO, Debian 13 Kernel 6.12 has overall worse latency, although with system setup tooling that you can get from Rodw, the latency can be improved a lot.
There is only one slight latency regression with the new linuxcnc-ethercat, the modulo operation that I currently must use to do phasing is causing slightly more latency on the servo-thread, and I want to fix that, I am preparing patches to modify Linuxcnc to expose a function to allow proper native phasing, so that I can lighten up linuxcnc-ethercat to match the older performance for both positive and negative refClockSyncCycles modes. Previously I was undecided if going that path, or using Sascha Ittner method/hack of moving ecrt_master_application_time out of lcec_main, but I found that Sascha's hack causes issues with papagno's hardware, I tried this with built binaries from Sittner repo, with refClockSyncCycles -1 nothing would move, therefore I am now convinced the proper path is to have a native linuxcnc phasing function, this will require updating both linuxcnc, and rebuilding linuxcnc-ethercat against the new linuxcnc-dev headers, hopefully the patches will be ready and merged soon, will try to keep you guys updated on the progress here, I know there are people following in the background

Europe started to make some nice changes, i was surprised, it did not last!
Now they're back at f@kin up, again, using "russian office suite" or whatever that fiasco was and still is, jumping in the "age verification" bandwagon, etc, but the "stop killing games" hearing was quite refreshing as most of them did agree and show support, waiting to see if that goes any further.
On the last subject, Epic Games effed up by deleting the old games and later did come through and released them free, namely Unreal, Unreal Tournament and UT2004, i still have the original Unreal CD and the Voodoo 2 3D accelerator i got back in the days.

Not my stuff.
