I'm sorry if this is wrong section! My sever was running for just over a week with no problems or lag at all. Now many of my players are experiencing chat lag and worldholes. I am hosting in the UK and playing off the same machine I'm hosting on. Currently anyone in Europe seems to be getting a fine connection, but US players are getting unplayable lag. My plugins: Autosave Essentials Heroic death ichat iconomy iconomychestshop jobs lockette mchange nocheat permissions worldedit worldguard What I have tried: restarting computer restarting server restarting router I am on a 10mb down and 1mb upstream fibre-optic broadband connection. My computer is not experiencing CPU lag, my bandwidth limit hasn't been exceeded, my upstream/downstream speeds are what they should be. I upgraded the server program to start with 4gb dedicated RAM on 64bit java JRE7. my computer: quad core 3.4GHz 8Gb RAM 64bit win7 64bit JRE7 Java I've tried when I'm not playing and just hosting and I get the same result. I've also tried on a brand new fresh vanilla server with a new world and it still happens. The server worked fine with 7-8 people simultaneously and now with just 1 American player they have massive lag. Basically everything worked fine and now my american players get unplayable lag - any suggestions would be much appreciated, I'll try anything.
