Minecraft server lag since updating to 1.8
My server has worked well since 2011, however, nowadays, since updating to 1.8 (actually some subversion of 1.8, not actually 1.8, but I went directly from .2, 3 or something to .8) it lags very much. This is an average message in my server log
[SERVER thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running x behind, skipping x tick(s)
The ticks can go up to 2000+ and 70000ms.
Now, you might think I have 60 plugins with 100 players but I'm running vanilla with max 3 players. I have allocated 2GBs of RAM.
Some of the problems I'm having is that everything is slow, I can travel and the terrain generates 1 minute later (unless I'm kicked with the reason "Timed Out"), or I might hit a monster and suddenly, 30 seconds later I am dead and the mob has walked 30 blocks away.

If the server is hosted by a external company, contact them about the server issues. This problem can also be created by your wifi speed, you may want to run a speedtest.net scan on your wifi to make sure nothing is wrong. Also, if you are the one hosting the server, try connection through localhost:(port) next time to possible reduce lag. And one last thing, you may want to check if its not just minecraft thats lagging, you could have too many things installed on your computer or too much RAM being used at the time. Also, you may want to consider lowering the RAM usage for 3 players, if you are only hosting a vanilla server, with few slots you DO NOT NEED 2GB, a bukkit server with 10-20 slots needs about 1 GB, so lower the RAM usage if your hosting and yeah! :)
