Game randomly freezes

At times, Minecraft might freeze for 5 seconds before recovering, this can be a issue when playing with friends as when you are in a battle, you freeze for 5 seconds giving others time to kill you. This happens very often and i hope it gets fixed in 1.11.5 or 1.13. Here's a clip of the bug occurring: https://twitter.com/min3rl3g4ndyt/status/1145833619652374528
