I wasn't referring to chat channels. I was referring to /tell commands. Who,
apparently, works (sometimes) while the rest is in limbo.
As there is no detectable client-client communication, this shows that the
lag problem is sometimes/often an intra-server lag, not a client-server
lag.
At other times, everything freezes up, as you experience.

I've done a tcpdump. There are 2 connexions I've seen used. One goes to the
login service (dimension load/character selection). The other goes to the
game service frontend. I haven't found out if you disconnect/reconnect from
the game service; I suspect not.
I'm maybe my graphics (love ansi art) should have put "client A", and "client
B". I was suggesting different clients, each connected to a separate process
that handle their frontend, not parallel TCP streams.

RDP. Proposed 20 years ago, never ever used :)

QoS in IPV6 is a lot better than the V4 version. At least, it uses more than
two bits in the header :)
