Lag Spikes making it unplayable

Running 1.13-pre1 and getting lag spikes every few seconds, making it unplayable. I have ran 1.12.2 just fine, not lag spikes at all. I'm not sure what the issue.

I did a force crash report (F3 + C) hoping that would provide some information on what the cause could be.
