Paper Vs Spigot Which Software Is Better For Your Minecraft Server

What one should I use on my server?

Spigot is considered more efficient than paper due to the optimizations made in the server code. It also gives users control over technical parts of their Minecraft server, such as specific redstone features to disable, TNT mechanics, and much more. MINECRAFT SERVERS

Paper also comes with its own much improved "v2" timings system. This allows users a deep dive into the server's inner workings, which is extremely useful for identifying areas of poor performance and lag.

Paper can also be used as a patch for Spigot bugs, so it may be more stable than regular Spigot. Both can be used for almost any use case because they have a large base of users.

Any server expecting to see even a modest player base should aim to be as fast as possible. Paper is an easy to use upgrade from Spigot. It can vastly improve performance with little cost.
