I have deleted them on startup. It took almost one hour 17:04:21-17:59:54 at a rate of ~167 records per second.

The register for Order Classes is common for Sales orders and Service orders. When I set an Order Class to create an Activity - it works for Sales Order, while for Service Orders - not. Is any setting...
