Why HDL taking too long to load the absence entries

Hello Experts,

I tried to load the 1120 absence entries in HCM Cloud using the PersonAbsenceEntry HDL. It took around 30 hours to complete the entire load. I noticed similar behaviour in multiple lower environments. What could be the issue?

On the other hand, through the Interface from Ebs, every week there are 20000+ absence entries loaded through HDL, which takes less than 2 hours to load. What am I missing here? Is there anything to check?
