First of all, i have 4 core with idk too, but still usable, 6GB of RAM, 20gb of SSD. Its a VPS with good network connection. I need a technique or a solution to proceed multiple actions: set skin, items, teleport, send custom packets, set variable... All in 1 command with as high TPS as possible. It's 1 player per turn in 1 second, with all the actions above. And it still drag my TPS down to < 1 just "a" moment. (2 second) I've tried to delay the time between 2 commands (the same command with multiple action), but it just drag my TPS down. My server is running at 30% CPU in normal. (Still handle multiple actions but not the same time). This is a minigame. I'm very appreciate with your experience of reducing lag. I want to know the secret of large servers on handling this.
