so i run a custom modded server for me and my friends. i notice with 60 mods, my client starts to lag with server running. my system specs: amd-fx 6300 3.5ghz asus gtx 660 dcu oc edition 8gb 1866 ram asus sabertooth 990fx wd black 1 tb 7200 rpm. newest java 64 bit

is there any way that i can increase gaming performance or decrease the server cpu usage to increase fps. i set my client to high priority stuttering is nearly gone and stuttering is now minimal. is there a mod, a plgin that i can use to stop my issue?

    60 mods? I'm thinking there's your problem. – Frank Apr 5 '14 at 1:22
  • @Frank Im running 147 mods with a 8 gig computer but i have 4.0Ghz cpu – LFM Apr 7 '14 at 22:00
  • Oh, 147 mods is nothing, I wonder why my client might be lagging? Hmmm... – DatEpicCoderGuyWhoPrograms May 28 '14 at 1:28

If ONLY the client is lagging: That is a CPU problem, as the server would lag as well if it was a RAM issue, and that would need to be taken care of via upgrading the CPU in your computer, or hitting Ctrl + Alt + Del and selecting Task Manager, finding javaw.exe (That's what it uses on my machine, it might be just Java.exe) and setting the priority to whatever you desire. If that doesn't work you may have to upgrade.

If both the client AND the server are lagging, then that would be a RAM issue and can be fixed by the solution regarding RAM.

  • You can check if the server is lagging by checking the console output for Can't keep up... messages. – MrLemon May 28 '14 at 11:00

The only way to fix this issue is to upgrade your RAM.

This is because hosting a server uses a certain set amount of RAM, Playing Minecraft does the same. Therefore causing your FPS to be lower then usual. If you do not want to upgrade your computer you can also change the amount of RAM used by your server. Which, There are Youtube videos for the launchers you might be using on Youtube. Remember this, You don't want to upgrade the amount of RAM it's using, You want to downgrade it. This will cause the server to not be as fast. But Minecraft will not lag nearly as much.
