, which (any way using the sqlplus) seems easy to coding than with the DBI pack.
Yes, there are multiple ways of doing that - you got most of them listed above.

Good
If you restrict your question to simple "compare the-known-to-be-suboptimal-sqlplus with powerfull-DBI" then: DBI is much faster than piped sqlplus. This is your answer. You can get it by running a simple tests.
The "parse" is not "parce". You should read about how the SQL is executed - then you would see that sqlplus needs to compile the statement as well.
If you can use sqlplus to execute data pump then you might use sql*loader engine and this might be much faster.
Try reading the answers above again - it should help you.
