Parts of The Other Dimension causing game breaking lag

[CrouchingPickle]

While exploring the other loading specific areas causes my client to lag heavily or crash. This world is being run on a server and the server is not crashing only my client. I have 12 gigs of Ram allocated to this pack.

While exploring for the piglich I have had to take long out of the way routed to avoid these seemingly random areas of lag and more recently I have had to teleport away from my piglich farm while getting 1 fram per 10 seconds.

Found a fix. For someone reason the game was spawning between 2000 and 5000 entities somewhere in the chunks loaded. Solved by /kill @e[distance=5..300] to avoid killing myself or anything within forceloaded chunks. Still unsure how this spawning is triggered or what is spawning.
