Star-Made running low on memory when landing on planet

[kiddan]

Title says a lot, I get errors that Star-Made is running low on memory when I land on planets and my FPS starts dropping. I also have no idea how the memory options work:

Any recommendations for memory options? I'm a complete noob with this stuff. :P

How much RAM do you have?
I recommend RAM-2GB for max memory[but no more than 8GB, if less than 4GB RAM, use half RAM instead]
I recommend half of max-memory for initial memory, but no more than 2GB
As for early-gen memory, I generally go with a quarter of initial memory.

Also if you do have more memory available you might only be able to use it if your running Java 64bit. Assuming your using a 64bit operating system as well. If not I think your still limited to 1GB of memory max which is what you already have it set to.

Also are you just leaving the ship on the planet or you built a docking system and docked to it. Letting a ship fall to the planet and leaving it on the surface creates continuous collisions causing a lot of lag.
