So, I have an AMD FX 8000 something. It's an 8-core, relatively powerful, 8 GB of ram. When I began our world, it was running a solid frame limited 60 FPS. It got down to 10 FPS anywhere in the world, I added Optifine, and got back up to 30-40. Now, it's back down to 15. (This is all outside of our base and all). It's all also running on a dedicated server(with 2 players). What could cause the increasing loss? My friend I'm playing with, is crashing every hour or so, but runs at a higher framerate. (Not actually crashing, just catastrophically freezing). I don't crash but I do lag quite bad. I am running Ubuntu if that matters, but this is Java, so it shouldn't.

 

Does anyone else have this issue? Solutions?

Minecraft isn't made to perform very well. With a lot of mods/machines/large builds framerate will bog down after awhile. Minecraft also doesn't use multicored processors very well so if you don't have a high base rate for the cores it might be a reason. Ubuntu might cause an issue as it is a different version of java and a different version of openGL. Linux is less supported as it's a smaller part of the user base.

I was able to make it considerably better by running the following command: 

free && sync && echo 3 > /proc/sys/vm/drop_caches && free

as root. Further research indicates this was unnecessary, however it is nice to run if your hard drive cache gets too big.

Bottom line was it needed more RAM available to Java.
