Minecraft version: 1.14.4 Forge server version: 28.2.20 I host a forge server at home on a Dell PowerEdge R610 to play with 6 friends. It have 96GB of ram and 2 Intel Xeon E5640. I run it on Debian 9. On the server there are 3 mods: BiomesOPlenty, MrCrayfish's Furniture and inventorysorter. It can't keep up, 15000ms behind. It's not my internet because in vanilla there is no problem. I search a lot but nothing useful. debug.log :
