Fluctuating run-time for Dataset refresh in Power BI service (Long data-set refresh time)

My Power BI report dataset takes a long time to refresh in the service. The time fluctuates a lot ranging from 25 seconds to over 10 minutes sometimes, while the size of the data remains the same. This can be understood with the help of this log:
