The ingestion rate of analytics incremental ingestion is lower than initial ingestion

Compared to initial ingestion, the ingestion rate of incremental ingestion is much lower, especially in the 99-collection test. All runs below were running with build 7.0.0-4454.

 
In the incremental ingestion tests, after the initial ingestion, we do the following steps.

1. disconnect
2. restore data (the same data we use for the initial ingestion)
3. connect
4. measure the second ingestion
