Hi Tiong Ghee Tan,
All the tables seem to be the sqlserver-related tables used for some audit purposes (events, sessions etc.) except workflow_context.
For workflow_context, you can improve the sql performance by optimizing the steps, decreasing the persistence, and redesigning the business processes. There are other advanced techniques to improve the workflow context sql performance, but this should be the first starting point.
What version of B2BI/MSSQL are they using? Is MSSQL an on-prem-based software or cloud service?
