TPS Decreases Drastically If Many Mobs at Once Fail to Reach their Target

Very similar issue to MCPE-64344, MCPE-114206, and MCPE-120605; possibly the same cause.

This issue existed in Java Edition also and was fixed years ago. See https://bugs.mojang.com/browse/MC-17630?focusedCommentId=92590&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-92590 for analysis.

While testing this bug, I found something very interesting and maybe useful to find the cause of the bug. I made a square boundary of two blocks tall and in the center made a piller of three blocks tall. I summoned dozens of husk inside the boundary and created an iron golem on the 3 blocks tall piller. To check TPS I used the same method used in the example video. The TPS was normal when there was boundary but when I removed some of the blocks from the boundary the TPS dropped immediately.

I am attaching a video showing this behavior.

anyone able to confirm this for 1.18.10? Tried the husk method mentioned above (with about 200 husks on win 10) didn't get any noticeable lag besides a small frame drop.

ive tested both setups listed here and i have found no noticeable TPS drops, measured both with server software and with snowballs. The problem probably lies with how powerful your device is, while lower end devices might struggle with this, other machines probably will not have a problem. Therefore, i truly wonder if this a bug or just poor device performance.

1.20.1 Switch OLED, Game Card

Noticed a significant FPS drop whenever Villagers (especially Farmers) attempts/pathfinds to work.

Ever since the non full block parity with Java (Mud, Path Block, Farmland, etc.), Farmers have difficulty pathfinding to full grown crops (as well as trying to replant) & simply stares at their "target crop" until their work period is over, with the FPS returning to normal.

1.21.41
Annoying lag, too many ghasts, short character freezes while all the mobs attack you and extremely slow generation

It is absolutely normal not to solve this problem for 5 years and not even listen to us
The important thing is to remove the exclusives on bedrock 😞

Hi) Is this still an issue in version 26.32 and later?

it is still an issue in 26.33

my mspt goes to ~50 with 100 husks and an unreachable golem (same setup as the example video), and drops to ~6 with 100 husks and no golem on a new flat world.
i used an addon (canopy) to check the mspt.
