So I've attempted to fix this multiple ways, modified spigot.yml and bukkit.yml. I've referred to: https://www.spigotmc.org/threads/guide-optimizing-spigot-now-covering-paperspigot.21726 for fixing, haven't tried PaperSpigot yet, but might end up doing so if necessary. Very randomly I've been getting many lag spikes, and just today the server decided to stay at an average of 10-15 tps, when before it was pretty decently operating at 20tps. Spigot.yml: http://pastebin.com/77enFD45 Bukkit.yml: http://pastebin.com/h8eZB71T I have the server restart every 12 hours, and the timings are all after a manual restart I did 30 minutes before, in attempt to fix the lag which started to occur. Timings from today: http://timings.aikar.co/?url=11813454 http://timings.aikar.co/?url=11843691 http://timings.aikar.co/?url=11843874 http://timings.aikar.co/?url=11843875 http://timings.aikar.co/?url=11843931 (Probably way to many) Unnecessary info (I think): http://gyazo.com/d8c470ddbdbfa6d6de9cedab23359d7a Yey... : http://gyazo.com/d70a6d033cbc50b532d49a2201d1d0ac Regarding server I'm running a OVH E5 1620V2, and SSDs - The only thing running is a bungeecord and this 1 server instance. Its never lagged this bad before, only minor lag spikes here and there every now and then. So.. Yeah. Help would be greatly appreciated.
