Hello,
For on-prem version typically the culprit for reports being slower or faster after upgrades, would be due to SQL Indexes and Index maintenance. SQL administrator would be ideal to look for and resolve fragmented SQL index, as that typically would improve performance.
If you need further advice and guidance on the matter, please submit a support ticket to our support portal.
Cheers,
