Will pausing the ingestion of some objects increase the overall ingestion speed of the Pipeline?

Hevo is horizontally scalable, which means that it automatically increases its resources with the increase in the amount of data being ingested. Thus, pausing the ingestion of some objects does not have an impact on the ingestion speed of the Pipeline.

You can, however, choose to ingest the Events more frequently by changing the Pipeline schedule. Read Scheduling a Pipeline for more information.
