I have experienced that huge CSV file (with several millions rows) import takes too long.
I found that DBVis inserts row by row which not the best way filling table with huge amount of data.
What about the batch execution of insert statements via PreparedStatemnt.addBatch() and PreparedStatement.executeBatch() (e.g. 1000 insert statement execution at once)?
It could provide better performance I guess not only for importing of huge amount rows but for slow DB connection where less amount of data is affected.
I would suggest to extend CSV import with batch execution.
