DB2 11.5 performance

Hi

We are looking into upgrading our DB2 from 10.5 to 11.5, and being concerned about the performance issues/regression, mentioned in
https://hclpnpsupport.service-now.com/csm?id=kb_article&sysparm_article=KB0076102 and other places.

Would like to hear, if anybody has done this upgrade and what the experience is. We are running BigFix version 9.5.14 and Inventory 9.2.16.

Thanks in advance
