SAP Sync is slow (SAPLicence Table)

Dear All,

I can see that Standart SAP R/3 connector Step(licensetype) takes 40 minute to sync 312 Object. When I checked Indexes on SAPLicense Table, there are 4 indexes but every Index covered with one colum. As far as I can see, indexes can be improve. Is ist possible to improve Indexes and make it Sync time more short? (We are using revision filter) Also  SAPLicense table has 312 entry for this SAP system.

This is not about hardware performance because as you can see in Screenshot, 26000 user sync in 42 minutes.

System: One Identity 9.1.1 Production and test are same.

Thank you in advance

Best regards

Samet
