About Sewlia
How's it different from Paper?
Sewlia is designed to address the constant bottleneck of the Minecraft server running on a single thread causing performance issues. It is by no means a drop-in replacement for Paper.
Is Sewlia for me?
Sewlia won't be useful for the majority of servers out there and will break most public plugins. It's ideal for servers with very high players counts, that offer gamemodes that naturally spread players out, such as SkyBlock or SMP.
