System takes lot of time to generate the SFO events and display in Monitor Fin.Orchestration Exe.UI

Summary: We have setup SCFO for across the LE Inventory transfers. The Inventory Transaction that we used is Inter Org Transfer- In Transit. Once the Inter Org Transfer Transaction is completed, the SCFO event would be triggered automatically and displayed in the Monitor Financial Orchestration Execution UI in less than 2 to 3 minutes.

But recently we are facing a lot of time delay in this process? It takes minimum 15 minutes to create the SFO events and display in the Monitor Financial Orchestration Execution UI. Also in our TEST environment we are creating this transaction with 4 lines only in a single transaction, but in the PROD it would be minimum 500 lines for a single Transaction, we are not able to identify how delayed it would be.
