That seems to help a bit, though initially it didn't look like it. It seems that I have stable pings if there is other activity on the network regardless of location services, e.g. a TM backup over wifi.

The connection looks very good, I can keep vpn and ssh connections open for days. It's just this latency variance that doesn't seem normal. I don't really have other clients to test with, just phones but those are all over the place with their power saving.
I think so. The memory test turned out to be very sensitive to any kind of load on the router. With WAN disconnected, wifi down, and all services stopped it gets over 780MB/s all the time. I traced my issue to dnsmasq of all things. I had it running with adblock and over 500K blacklisted domains: even with no load, dnsmasq would use 100% CPU for a few seconds every two or three seconds. The test was probably getting interrupted too frequently.
Here are the results without adblock.
MacOS does periodic (and very frequent in my mind) WiFi scans for location purposes and the latency jumps to 300ms and more. I wish there was a way to disable those wifi scans.
Probably not much representative, because I am using the perf governor, WAN is disconnected, wifi and most services are down. Nothing weird in the logs, so I will put it on the live router shortly.
FWIW, I am seeing approx 1/3 drop in CPU utilization during dslreport speed tests on my slow connection (50M/10M) with SQM (cake). I am not gonna bother running 19.07 any more.
It does not: the difference is meaningless and impacted by the background workload. You would have to disconnect WAN and all wired clients, stop wifi, and shutdown all unnecessary services to get a true reading, which was over 770MB/s I think.
