Random TPS drops?

  1. Hello, Vince here!

    I've been having an issue with Bukkit and TPS drops for a while now.
    I then switched to Spigot, and the issues still seem to occur.

    The TPS is obviouly not very bad in this image, however at times it goes down to around 2 TPS.
    At the time of this image, 10 players were online.

    This is worrying because I often have 100+ players online..

    Why would this randomly happen?

    Any help appreciated!
     
  2. I was just on your server and it was running perfectly fine with 15-20 on. The server was responding perfectly (which it wouldn't at 17tps). Seems to fluctuate at random times?
     
  3. Yeah it does, it just happens randomly and it's really frustrating :/

    /timings didn't show any issues either..
     
  4. I checked your plugins, but didn't really get a good look at them. What do your custom plugins do? I can tell you that if it's happening randomly and timings aren't showing any issues, it's either a plugin (unlikely) or your hardware (more likely). I know your hardware is strong, but it's something to check on.
     
  5. How did you check my plugins.. 0.0
    /pl and /plugins = blocked
    query = disabled

    Also about the hardware, the CPU is nowhere near full use and the RAM is not even half used..
     
  6. /pl is not blocked, nor is /?. I was on your PVP server.
     
  7. This has been happening to me, except the issue is with mobs. 230 players, 2.7k+ entities will drop the TPS to around 10-13. /butcher will instantly bring the TPS back to 20.
     
  8. Yes, is there a fix / cause?
