My story started sometime before around August last year when synergy started getting really annoying with stuttering. Pretty sure it wasn't like that when I first started tracking 13-current in around May 2020 (I was on 12 with scfb for a long time before that with no issues), but since then I have tried to eliminate as many variables as possible. First I switched to barrier instead of synergy. Shortly after that I realized it was happening all the time and not just a network problem, I started using foobillard to verify during tests. I tried different RAM combinations, different network cards, a variety of RAM timings, stripping rc.conf etc, powerd settings, also scfb, with no effect. It is observable with ping -f, a dot or two appears every time it glitches. It seemed much better with RC2, but now with RC3 it seems to be back with a vengeance, and since its my main workstation and barrier/synergy server host for several machines, it is unbearable to use. Both Win10 and devuan3 on the same machine are smooth with no issues. Any feedback or info would be appreciated.
