Minecraft consumes excessive amounts of RAM.

Today I opened Minecraft in the new version and I realized an important performance issue. I play at 28 chunks and I have 16 GB of RAM and a Ryzen 7 4th-gen CPU, and it hadn't happened before to me, so I restarted the game and the performance got slightly better, but then turned worse in the span of a minute. I decided to start task manager to see what was happening and apparently 70% of my disk and 90% of my RAM were being used, and Minecraft was the application that was using the most of both; 60% of my SSD and 10GB of my RAM. I don't know if this happens only on my device as I haven't done much testing, but I believe it has something to do with this hotfix.
