GC speed after update 3 to 4

[rontex]

On two servers after upgrading from version 3 to 4, the garbage collector speed dropped by 2 times. Before that, version 3 with all updates was installed on the servers. The settings and parameters did not change.

Nothing changed on our Server after upgrading. 5 till 10 seconds as usual.

When GC is performed in seconds, it may not be noticeable. My GC was performed in 6-8 hours and became 12-18 hours.

What's the size of the datastore?

500Tb.
I noticed that on the second server after updating the kernel to 6.14.11-1-pve the problem went away. I rebooted the first server to use the 6.14.11-1-pve kernel, I'll see. I'll write about the fact tomorrow.

That's right. Updating the kernel from 6.14.8 to 6.14.11-1 solved the problem.
