Reading the replies, there are some misleading comments like “there will be more channels so it should be fine.”
The amount of channels don’t really matter, it’s the servers if they have upgraded or not (which surely they have to have done for this uncapped beta registration). They could have 100 channels but if the Servers can’t handle the amount of people online at once, every channel will lag regardless of how many channels there are.
There’s no public estimate for how much capacity the servers can handle.
(channels are made for mobbing etc and it does help with lag ofc with less crowding but the main issue is if the servers can handle the amount of players online at the same time. Two different things in a technical point of view)
As someone said already, this is just a stress test for the new Servers they have.
