Introduction When I say Lagplex, I really mean Mineplex's tendency to lag. From what I have gathered, Mineplex currently runs on Spigot (A type of server). A few years ago, people realized that Spigot had become slow, inefficient, and that it could be HEAVILY optimized. The open-source Spigot repository was forked and Paper was born. Over recent years and months, a few more types of servers were created: Purpur (a fork of Paper; designed to add a few more handy features to its API) Tuinity (a fork of Paper; designed to increase preformance for large servers) Yatopia (a fork of Tuinity; designed to be a hyper efficient form of Tuinity) Why Mineplex Should Switch As you may know, Mineplex used to be the largest server on the block reaching a peak player count in the mid to upper 30k's. Since then, Mineplex's player count has decreased quite a lot; however, Mineplex still regularly gets 2,000-4,000+ players a day making Mineplex a large server requiring a more efficient, fast, and HEAVILY optimized server jar to run on. What Mineplex Should Switch To Your first instinct might be for Mineplex to switch from Spigot to Yatopia; however, Yatopia is very new and buggy. Not to mention that most patches for Yatopia could and will be applied to Tuinity. So, the next best thing is Tuinity. Tuinity would increase preformance for large servers, like Mineplex, and would push Mineplex from the days of 2015 (Spigot's prime time) to 2021. Conclusion Mineplex is running on a very old, inefficient, and slow server jar. Mineplex should consider to upgrade its server jar from Spigot to Tuinity (or, at very least, Paper).
