Most common complain (not my main problem)
What most part of people complains about CH reduction are a variant of a KS [KillSteal, a player killing a mob that should be his] occasioned by less mobs on the map. That is not my problem, but is a big problem too. (I tell about my problem below).

This (the KS competition) Generates two main problems.
Problems to Grind and problems to complete Quests, since in many quests players need to kill mobs in order to complete the quest.
At the beginning Clerics and Swordsman suffer more, simple because they waste time until reach the mob, so the mob end up being killed by an archer or wisard, but at the middle game to the late game, this is more general.
KS will occur not only because players are on the same map. Yes Bots and Summoners will be too. But in reality players are the main competitors, the others just add some value to this competition. Sometimes, one more channel on normal maps is enough to solve this issues, as players can try a seconds spot without have to deal to the same player competitor again.

My problem
Is about Performance. 

I know opened channels with barely no players have a Cost. I already worked with amazon servers for example, and I know when the company need to borrow more processing, they also need to pay more. In this case server need more processing just for few players who want to be separately from the others, or have more space.
But I would recommend: Let at least 2 CH on each map to improve game experience, at least when the 1st channel reaches 20 players on the map. I know a channel can keep more than 50 players, but the performance for some players decrease to zero with much players on the map/ch.
The Truth be told: Tree of Savior have a Horrible cleaning of memory cash, what means that the objects created (objects of programming language) are not properly cleaned out of the memory. So, on computers with low specs, specially when comes to memory ram (4 GB still generates problems), the game causes an StackOverFlow after change to two or three maps. Not only this, the animations itself and the change of this animations of the game consume more process than many 3D games with for pc with high specs.
Generally on channel 1, you have not only the players, but Guild Towers, players Stores, Pets, players making potions. This means more objects to the memory.
People who have this error of stackoverflow just close the game and open it again to not be disconnected in the middle of a Saalus Missions for example, and have lots of patience.
The problem with performance on low spec computers are that with the reduction of the channels not only make this errors of stackoverflow come more fast, as make the lag much bigger as time pass, even if the error don’t occurring. Sometimes when there are more than 20 players on the map, the lag is instantly. Add that to the KS competition, and there is not way to play sometimes.
With this, the optimization updates will mean nothing. Will just kick out this type of players.
I already saw many threads about create a function to players to choose what channels they want Before moving to cities for example, exactly because when we move and are let directly to channel 1, the game crashes or the screen become almost frozen.
The last problem is that by forcing players to play on this conditions, the PC will burn as he**

I know this can be for 10% of the players or less, since the great mass of low spec computers already left the game, but this is my feedback.
The key in this case is not wait channel 1 reaches 35 players or more players, to open another channel, but do it at a low quantity, like 20 players. That is my tip.
Any one having some issues like this or want to comment I will be glad to respond, if not just a troll.
