When I was recently clearing out an ocean monument, I noticed in the very specific area where my base is, when I mine a block I get about 1 FPS for a second or 2. Normally I would be stable at 60 FPS. This lag is severely worsened when mining underwater and makes normal play near on impossible, as it occurs in a more minor form when placing blocks too. This tends to only occur around a beacon or ocean monument.

When this happens, please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report (minecraft/crash-reports/crash-<DATE>-client.txt) here.
I think this issue might have to do with allocated RAM. I was giving MC 3GB or 5GB. I'm told odd numbers aren't good for performance and MC starts struggling after 4GB. Giving MC 4GB seems to have fixed it, although it's been a while since I made the change so there may be something else involved.
I'm getting a similar issue and it's steadily driving me insane. Even if my issue isn't the same, maybe some solution here will help me too.
I'm not using a beacon or conduit, just an efficiency 4 diamond pickaxe.
I notice it most when chopping down trees. I haven't noticed it underwater. I think it's better/worse in different areas but I can't quite tell.
I've seen some people with similar and older issues saying that it helps to lower Minecraft's RAM to 2GB or less. I haven't noticed this helping, just lower overall frames, but the frame drops when breaking blocks are still there.
