Hello. I am looking a way to diagnose strange bug, when ping indicating absolutely normal values like 20-50ms, but egress UDP is highly delayed (usually 200-500ms, up to 5s), like uplink ISP queuing traffic. This issue can be catched visually/audibly with voice/video streaming (twitch, google meet) or gaming and reproducible on 2 ISPs (cogent and one smaller local) with guaranteed channel (small office) with different routes, but winmtr, mikrotiks traceroute or pingplotter dont show abnormal behaviour.
Mikrotik hapac2, any firmwares from 6.4 to 7.6 now with defconf.
I have few VMs in different locations, including googles, so any advices appreciated.
