Beacons on Realms are EXTREMELY laggy.

Beacons with haste 2 are basically useless because it just gets tons of block lag. I don't wanna mine blocks 4-6 times each just to clear an area.. its unnecessary. I've been noticing a tremendous amount of lag and block lag issues especially on Realms. I am not going to continue to pay for a server that barely works... PLEASE FIX ASAP
