Hello Nuttapol,
The both statistics seems front end statistics. You have to analyze first at OLAP perspective.
Check the query statistics on RSRT - DEBUG Mode - Display Statistics.
With that, compare the both scenarios.
You could be experiencing some front end performance issue and associating with Hana.
If the issue is clearly visible on RSRT, we can track down the events that are consuming more time.
Best Regards,
Edward
