Improve parallel processing performance of Refresh

Ongoing project is planning to do initial DB construction using the Refresh function of CCDC to CDC. There are many View definitions in the CCDC, the logical table becomes over 800, and we want to improve the overall throughput . Specifically, we'd like to reduce the currently estimated time to one third. We are considering realization by dividing Subscription into two or more and refreshing at the same time, but the performance of parallel processing does not come out as expected. In the actual measurement there were two subscriptions to refresh from different IMS DBs, requiring 7 minutes and 6 minutes. Even if it was executed at the same time it took 12 minutes without completing in about 7 minutes. It is only about 10% shortening when executed serially. Therefore, even if Refresh is executed in parallel, we want to have the same throughput as running independently.
