After upgrading the Ubuntu server from 1.16.40 to 1.16.100, I am seeing large lag spikes, far more regularly and with longer duration than ever before. A few times per minute, players will lag for 2-4 seconds, after which the entities will either rapidly jump to their updated positions, or sometimes not move at all. During the lag spikes, players cannot pick up items, attack mobs, or even open the inventory screen.
I haven't changed any aspects of the host machine or environment whatsoever between the before and after. It must be some behavioral change in the new server version that's causing this.

I can confirm this is happening on my server as well. We started a fresh world with the update. No redstone builds yet, but the lag spikes are terrible! Prior to the update, our old world didn't significantly lag unless we had 8+ players on at once and we had a lot of redstone contraptions.
This is our current server hardware:
Intel Core i9 9900K up to 5.0 Ghz
Unlimited NVMe SSD
DDR4 ECC Ram 2133/2400mhz
Since the update, when only 2-3 players are on, the lag is horrible and the lag spikes seem to be constant and random.
As a side note, I did experience tons of lag in a single player world while looking for the new seed for our current world. I was the only one on and in creative mode.
I also want to report that the lag is causing mobs not to spawn, passive or aggressive. We play on hard mode but it's more like peaceful. The only mobs that spawn normally, that I've noticed are drowns. Very few mobs are spawning in the Nether.

can confirm, this is happening on my server too. Seems to happen in normal worlds though as well
