What is Cross Server Core ?
Cross Server Core is a minecraft library that enables cross server communication between minecraft servers. It uses RabbitMQ for reliable direct data transfer and MongoDB for delayed data transfer and data storage. It really start to be useful when you have these multiple minecraft servers connected on a proxy.
What is it used for ?
In my case I use it to enable player transition between different server instances. I can with this mod transfer player inventories, states. I can also create a home and tp system between servers. I use it to synchronize other mods like FTBTeams, FTBQuests, Waystones

Server lagging with CrossServerCore – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CrossServerCore consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
