Hi everyone, My server got low TPS when reaching ~140 online players, and I have no idea of what is causing this. I already tweaked everything in spigot.yml (spawners nerf, low mob spawn rate, ...), but TPS still drop. I know I got some heavy plugins (i'm working on fixing this) but I don't think that plugins are the only cause of 15/16 TPS avg. Server specs: Intel Xeon E5-1650v2 6c/12t 3,5 GHz+/3,9 GHz+ 128 Go DDR3 ECC 1600MHz (20 go allocated to minecraft server) Timings: http://timings.aikar.co/?url=10962479 Other timings when getting a huge lag spike: http://timings.aikar.co/?url=10971319 spigot.yml: http://pastebin.com/eefMjXrz bukkit.yml: http://pastebin.com/gyqKuvPL If someone could help me improving my server performance it would be great . Thanks !
