Solving problems with lags

I have heard that the server has a problem with Special Deals. There are several solutions to the problem. I suggest that the money from the sale of SP will be immediately transferred to the selected storage (instead of an email). If this is not enough, I suggest that the items are sold automatically when picked up by the player.
You can also turn off dropping items in a party. But you would have to increase the price of trash items and lower their weight to 0.01 lt and artificially add some items through the server to the market place.

I think you should consider the appearance of bosses on several channels at the same time. At the moment, several hundred players are constantly migrating between channels, which causes unnecessary lags. You can also make an additional channel for bosów (without mobs). or use a siege channel for this. Bosses should not appear during node war (this should be entered quickly).
