***UPDATE: It has been determined that the culprit is Minecraft 1.8.x. Chunk loading was modified for 1.8 and this issue does not occur in 1.7. As of 16w02a, the issue persists in snapshots for 1.9.*** I've been having an issue with my server for a while and have been unable to resolve it. Whenever a player logs into the server or teleports to chunks he doesn't have loaded, there is a considerable amount of time between when he logs in/teleports and when he can move around and do things. The login/teleport is nearly instant, but it seems it takes a while for the server to catch up. Here is a video demonstrating the issue: Here is what it looks like to other players: Here are the server's specs: Xeon E3-1276v3 CPU (4 cores, 8 threads, 3.6GHz) 32GB DDR3-1333MHz RAM 250GB Samsung 850 EVO SSD + 1TB WD Blue for backup 1Gbps connection to the router, 150Mbps Internet connection, 100Mbps connection to the local network (we have CAT5 running in our house) All servers tested are running Minecraft version 1.8.8 Here are the steps I have taken to investigate the issue (none of which helped bring me closer to the cause): Play over the local network Play over the Internet Play on a vanilla server hosted on the same box while the main server wasn't running (to verify that it wasn't a Spigot/Bukkit issue - it's not) Switching between Craftbukkit and Spigot Testing different storage devices with varying speeds Here are the steps I have taken in attempt to resolve the issue (none of which have resolved the issue): Switch between Craftbukkit and Spigot Upgrade to a faster hard drive Upgrade to an SSD Allocated more RAM to the server Turned down the server's view distance from 10 chunks down to both 5 and 1 Here is a timings report for my server: http://timings.aikar.co/?url=13286497 Here is my server launch script: http://hastebin.com/elicexugek.hs I have been at this for months now and have made no progress towards resolving the issue.
