Details of the issue so i started a server and everything was running fine for over a month i would say. and me and a few friends would play and there would be 0 lag. now the server says it cant keep up and everyone is lagging none stop. i was looking at how to fix this a lot of post say add more ram and CPU power to your computer
i was looking at how much it was using while running it was only using 1700MB of ram so less than 2Gigs. and i have 12 gigs in the system i have been trying to give it more ram but i cant seem to find the best way to do this. i tried to edit the start server file i tried to make my own. and that didn't seem to help. when i say how little ram it was using i wanted to also tell it to use more cores on my CPU and there seems to be a lot of different ideas on that topic to some say MC can only use one core some say it can use two. i saw when the server was running it was using 13% of my CPU and I really want to give it more its an 8 core AMD possessor it is pretty powerful but i am struggling at how to tell my server to use more of the system i built the spare PC with leftover parts so all it has to do is run windows and the Minecraft server. i have looked on how to dedicate more ram to the server can someone link me to pages on how to give it more cores. i tried setting the affinity but that was already done. this is more 1.10.2 all the videos and post i find are for old versions please respond if you need more information from me to help out.

Sounds like you have built something that is eating all of the CPU of the server. So first thing to check is the /forge tps command. All of the dimensions and the overall should be at 20 TPS and under 50ms. If they are not that is a symptom of the issue and it should tell you which dimension is actually causing the issue. Usually it is the overworld. Next if your TPS is below 20 use the tick profiler on the server.

https://github.com/nallar/TickProfiler

It doesn't need to be loaded on any of the clients just the server. Use the commands to run a profile for at least 30 seconds (longer might yield more accurate results). That will tell you which chunks are the the TPS spikes as well as report what entities or blocks are causing the issue. What it will not tell you the specific location of the problem. It will be a little more generic like tile.TileExport would be some export bus used by Refined Storage. Once you know what mod/block/pipe is causing the issue you can start breaking the block type and doing another measurement/profile to see if that helps. Usually it will be a specific item/location causing the problem.
