      Description

      Mod Notice

      We are now closing this issue, because it has grown too indistinct. Note that this does not mean that we think performance is perfect - we will keep working on performance optimizations for future versions.

      However, this Jira issue in specific has outgrown its usefulness, containing a range of different concerns all mixed together. If you still experience performance problems, please identify what the scenario is and submit specific bugs, so separate issues can be tracked separately. Also please make sure to include debug reports and all relevant information when reporting such bugs.

      Note: Jira is not a discussion forum. If you have performance issues, follow the instructions above rather than posting further comments on this issue.

      This bug can have multiple symptoms, including, but not limited to:

      • Blocks reappear after being mined
      • Entities don't move
      • Chunks don't load and when entering them, the player falls out of the world
      • Cannot open chests and other containers
      • Cannot interact with entities

      Also, when this issue occurs, the a line like this:

      Can't keep up! Is the server overloaded? Running 5000ms or 100 ticks behind

      will be printed occasionally in the game console.

      Sometimes this issue will become so bad that it will crash the server. In that case the crash report usually has a line like Description: Watching Server.

      If you experience this issue, please run a complete debug dump by following these steps:

      1. Generate a debug profiling (.txt file):
        • Run /debug start
        • Wait for a few minutes
        • Run /debug stop
      2. Generate a debug report (.zip file):
        • Run /debug report

      Those files will be generated in the debug folder of your Minecraft instance. If you are on singleplayer, access your game directory. If you are on server, report to your system administrator. If you don't have op permission, either ask your server admin to perform the dump, or if you are on singleplayer, open your world to LAN with cheats on.

      The bug

      When my "ms ticks" is higher than normal, i can't place/remove blocks, drop/pick up items, use items like a carrot on a stick. Delay between my action and world's reaction are extremely high.

      Upd: in snapshot 18w45a ms ticks is still really high in normal world when mobs are spawning. Chunks stops rendering sometimes, items cannot be picked up etc.
