Low TPS!

Discussion in 'Performance Tweaking' started by Bouger, Jun 26, 2013.

  1. Lately I am having low tps when the server is full (175/175).
    My dedicated server:
    32 gb ram
    120 ssd
    10 TB traffic
    100 mbps.
    e1240-v2 3.4 ghz.

    Thank you!

    Everything is fine and perfect except for your Entity Ticking, Try turning down the Entity Activation Range in your bukkit.yml
     
  3. This is my configuration of my world:

    world-settings:
    default:
    growth-chunks-per-tick: 650
    mob-spawn-range: 4
    random-light-updates: false
    aggregate-chunkticks: 4
    item-merge-radius: 3.5
    exp-merge-radius: 3.5
    wheat-growth-modifier: 100
    cactus-growth-modifier: 100
    melon-growth-modifier: 100
    pumpkin-growth-modifier: 100
    sugar-growth-modifier: 100
    tree-growth-modifier: 100
    mushroom-growth-modifier: 100
    entity-activation-range-animals: 32
    entity-activation-range-monsters: 32
    entity-activation-range-misc: 16
    entity-tracking-range-players: 48
    entity-tracking-range-animals: 48
    entity-tracking-range-monsters: 48
    entity-tracking-range-misc: 32
    entity-tracking-range-max: 64
    info: true

    What would be the recommended change?.

    growth-chunks-per-tick: 650 - turn down to 500


    entity-activation-range-animals: 32 - Turn down to about 20
    entity-activation-range-monsters: 32 - ^
    entity-activation-range-misc: 16 - Only needs to be about 6
     
  5. Just half the chunks loading and tune down view distance if you really want a tuned performance at your thresh hold.

    EntityTick is still quite high - try turning down the Entity Activation Range in your bukkit.yml even more, or making less entities spawn.
    You could also remove every entity in the world after about 5 hours with a plugin.
     
  7. Isn't in the spigot.yml
     
  8. How about setting up automatic reboots on your server?

    I've found that rebooting mine every 12 hours keeps the server at a healthy TPS.

    Get a plugin that automatically shuts down your server after a certain time, then change your start script to this:

    while true
    do
    <Your command line here> (e.g. java -Xincgc -Xmx4000M -jar craftbukkit.jar)
    echo Its off.. sleeping for 5 seconds
    sleep 5
    done
     
  10. Or you can use RemoteToolKit
     
  11. Quoting vemacs:
    This would also do well for scheduling restarts.
     
  12. I personally use McMyAdmin for the automatic reboots :D
