Lag in Realms

Hey there! Recently I've been experiencing massive lag within Realms I play on. It's typically small 2 to 3 second delays however each one happens when specific actions are preformed. Upon opening chests, shulker boxes, e.t.c the game produces lag spikes and then everything becomes normal again. It may not seem like much, but it's causing tons of trouble on Realms and I really hope you can fix the issue.
