I am currently having this exact same issue. Only occurs on a Minecraft realm/server and not at all on a single-player. It started with the 1.14 update and I haven't had any performance issues prior to the update. I have tried many fixes for myself but none have worked.
The issue occurs the most with cutting wood and breaking leaves. The worst lag out of all of it comes from breaking bamboo.
