I'm sorry for my bad english.
I have a problem. CPU goes up too much while entering the game and teleporting. There is a 3% increase with a single client.
There is a 13-15% increase with 4 clients.
I checked the input_login.cpp Entergame function. I compared it with different. The problem does not appear.
Server Memory : 4GB VDS, not localhost. There are no players on my server. This is a test server.
BSD 10.3, Mysql 5.7
Connecting with 4 clients at the same time : BSD TOP :
