Very big and consistant lag spikes

So recently I have been playing the newest village and pillage snapshot and everything is great until the lag spikes kick in. I dont know if its the games optimization with hardware but something needs to be fixed. My computer hardware is more than enought for Minecraft to run. This also has been a problem with 1.13. It may be from the more detailed oceans. Can you please look into optimising the world. Thank you.
