Perhaps I have created this topic in vain and this question has already been resolved, but I can not find answers to it. Now I use Spigot 1.14.4 in conjunction with bungeecoord, without mods, only technical plugins like LogBlock AuthMe-LegendChat etc, with the most vanilla game. The maximum number of slots on the server is 25, the drawing range is 6 chunks, 20 ticks per tile and 20 ticks per entity, 8 GB of RAM is allocated for the server. The i9-9400F processor and all related components. But even under such conditions, on version 1.14.4 with 22 players, the TPS lag begins to go up to 16 units, with full online of 25 people - 10 units. On this hardware configuration of the server server on the spygot version 1.12.2, I was able to easily place 50 people with minimal delays (bunkers and heavy redston schemes still make themselves felt). How are things with performance on version 1.15.1? Any reviews of vanilla server administrators? Is there a chance to see 30 people online without lagging behind TPS on a clean vanilla server?
