VB.Net write large amounts of data to SQLite-DB
Executing thousands of inserts one after another is indeed insanely slow. It will help you tremendously to wrap all the inserts into a transaction.
Using t As SQLiteTransaction = sqlcon.BeginTransaction 'sqlcon being the SQLiteConnection For Each row As string In t line = Replace(row, "|", "','") cmd.CommandText = cmd_string + line + "')" cmd.ExecuteNonQuery() Next t.Commit()End Using You basically collect all the inserts you want to do and when you are done they are all executed in one large swoosh. This speeds things up a lot.
Here is a tutorial on transactions:
