get a better server TBH pocketmine.yml isnt some magic thingy that will make your server perform better then it's capable of
If you think there's a problem the first thing to do is to create a timings report and post the link to the results.
Best pocketmine.yml settings auto-generated one with a small tweak the only thing that I changed is PHP: anti-cheat: #If false, will try to prevent speed and noclip cheats. May cause movement issues. allow-movement-cheats: true u will always have cheaters, but this way they won't have knockback and even if u have a fast loading server (like me) 32gb ram SSD and 1gig internet up/down you will still have movement issues at some point and a ban is easier done, than creating an account
not on mine ... unless i somehow used a different version back than that did not have this by default so yeah if default forget it ^^
