Description of issue:

___As it has always been, some lags are felt during the generation of chunks, in 1.14, it is even more remarkable. I explain my problem: on my timings report, use the time to guide you in what I realized. Around 11:30, I started to move in fly and without running, in right row, where the peak of tps lost started. However, I stopped all movement after 5 minutes, ie at 11:35. And as you can see, the tps continued to fall, (the RAM consumed exploded -> 7Go) and I was unable to perform almost any interaction (rollback), 20 minutes after my stoppage of travel. I do not really find it normal, would it be related to async chunk loading ? Thanks in advance :) Don't hesitate to ask me for more details !___
