I recently made a small tekkit server for me and two friends, but it has been pretty laggy. I think this is because when making the server, I had to change the values in the launch.bat file to 1G. I was looking in several places and they say this happens if you have a 32-bit OS or 4G RAM or less. However, I have 8G and a 64-bit OS. Is there any way for me to add more RAM to the server or am I stuck?
