opps..this is not an "apples vs oranges" comparison.
Talking about 100 seconds is a mistake. The OP asked: The problem with this approach is that the CSV file (40MB) is loaded to DBI engine 5,000 times and takes hours to process. Answer is NO!: The answer that the OP wants can be had very fast and it is related to to the indexing of the database.
