What is data flow buffer in SSIS?

Why is SSIS so slow?
Assuming the package executes on the same server as the target/source database, it can still be slow as the Data Flow Task is an in-memory engine. Meaning, all of the data that is going to flow from the source to the destination will get into memory. The more memory SSIS can get, the faster it’s going to go.
