BP module very slow with IcingaDB backend

[MarcusCaepio]

Hi all, after switching to IcingaDB as the only backend, loading the configured business processes takes very long. On the old backend, they were loaded immediately.

To Reproduce

1. Have icingadb running as only backend
2. Check your defined BPs

Expected behavior

Showing the BPs as fast as with the ido backend

• Icinga Web 2 version and modules (System - About): Icinga Web 2 Version 2.11.1 businessprocess 2.4.0
• Web browser used: Chrome
• Icinga 2 version used (icinga2 --version): version: r2.13.4-1
• PHP version used (php --version): PHP 7.4.3 (cli)
• Server operating system and version: Ubuntu 20.04.4 LTS

Cheers, Marcus

Additional info: We figured out, that only one of our BPs takes very long for loading. This BP has many existing parts of other BPs imported. Maybe that's the reason?
