Steps to reproduce:

1. Update Zabbix server from 7.4.8 to 7.4.10

Result:

Hello. After the update, the housekeeper took longer to run. Previously, it took about 2000 seconds, but now it takes 4000+. No configs have changed. The database size has also remained the same (135 GB).

Zabbix is running on one virtual machine, while the database (PostgreSQL 17.5) is running on another. Both machines are running Rocky Linux 9.6.

The first screenshot shows that the cleanup process takes twice as long after the update. In the second screenshot, this can be seen in the graph.

The log shows that more hist/trends entries are being deleted, but by ~40% instead of twice as much.

I would like to know what caused this, as I did not see any changes in the housekeeper functionality in the patchnotes.
