Hello Spigot forums, Thanks for taking the time to read this post; it's going to be a lengthy one. Before I get into the issue itself, I am going to provide some background information so as to help diagnose the problem I am having. Background I am a server owner of a semi-vanilla Spigot server, and our server runs on minimal plugins and we do not use any heavy or memory-intensive commands (to my knowledge); however, we do NOT have a world limit, and we have players who travel out very far distances (ranging from thousands to hundred of thousands). Additionally, my server CURRENTLY has, on average, about 15-30 people online at one time. I do expect this number to go up with time, as before we had so many technical difficulties, we had around 70 players on at our peak. Additionally, here is the full list of plugins that my server has, with links to the respective BukkitDev pages. Also, I have taken the time to make sure every plugin is running the latest STABLE version available. AdminPrivateChat Enjin Minecraft Plugin Essentials(core) EssentialsChat EssentialsSpawn NoCheatPlus PermissionsEx PlayerLink Portals SafeEdit ScheduledAnnouncer2 VanishNoPacket Vault Votifier WorldEdit WorldGuard Hardware I am currently an Intel Xeon E3-1230 V2 server from Limestone Networks, and our specific server is located in Texas. The stats on this server are as follows: Core: Intel Xeon E3-1230 V2 RAM: 32GB DDR3 ECC This is not to say the server is using all of the RAM -- scroll down to Diagnostics Hard Drive: 750GB SATA Uplink Port Speed: 100mbps Bandwidth: 5TB Operating System: CentOS 6.4 (64-bit) My actual server is managed on this Limestone Network dedicated server using the Multicraftcontrol panel. Additionally, I am using the paid version. The Problem The problem I have been having on my server is countless and several players logging on and complaining about significant amounts of lag. The thing that really bothers me about this is that the people complaining about lag have capable computers and usually exceptional Internet speeds. The lag varies from being so terrible that they complain about not being able to hardly move, to times where there are just severe lag spikes. It doesn't make sense to me as to why this is happening, especially for the fact that when I used to rent a server from Minecraft hosting company EnviousHost, the people who are complaining about lag now did not have issues before the switch. This is what really confuses me. Additionally, the same players say that it seems to be on and off. There are brief times when they can play without lag, but more often than not, the lag renders playing on my server impossible. Extra Note: I've had numerous players say that the lag is only occurring in the overworld and NOT in the Nether or the End. I assume this is highly relevant, but I am not sure what to make of it. Diagnostics I have tried countless different things to try to optimize the server for better performance. Firstly, as mentioned earlier, I have made sure all my plugins are up-to-date as possible, and at that, they are all using the most recent STABLE versions of the plugins. I am not using any developmental builds for any plugins. Secondly, I had some people perform ping tests and traceroutes to the server, and for most of these players, they are receiving pings of less than 70s and their traceroutes have apparently been reliable. You can see the ping test and traceroute of one of the players of my server by clicking the respective link. Thirdly, after recommendations of the #spigot IRC people, I had the problem players download MRT, the tool for combining ping tests and traceroutes together to test for packet loss. I had two players run this tool, and you can see their results here and here. Finally, I had originally had my server set to use 24GB of memory on Multicraft, but after the recommendation of the #spigot IRC people about garbage collection, I lowered it to 8GB; however, this is having little improvement, if at all, for the people who are complaining about lag. Timings I took a timing of my server last night, and here are the results: Original paste In the timings viewer Server IP Finally, if you would like to log on for yourself to see if you experience lag on the server, the IP for the server is play.crystalcraftmc.com. I'm not trying to advertise, but I figure it might be helpful for some of you if you want to log on and see if you are having issues. What confuses me is that someone from the #spigot IRC channel logged on from New Zealand and he said he experience 0% lag, which really threw me a curveball… anyways, hopefully that may help you diagnose the issue if you want to log on and see. Conclusion I hope I have included all of the relevant information to help diagnose whatever issues it may be that my server is having. None of this making too much sense to me as to why the server is causing lag for our players… hopefully, this can help yield some results. If you need to know ANY more details, please just ask! Anything that may help is worth a shot.
