When we performed bulk insertion with Oracle as specified in the document, it transferred 200 data in 10 seconds. How can I do this more efficiently?
public async Task InsertAsync()
{
var items = GetItems();
using var connection = OpenOracleConnection();
var transaction = connection.BeginTransaction();
await connection.ExecuteAsync(@"insert into TableName
(Column1, Column2, Column3, Column4, Column5, Column6, Column7, Column8 ,Column9, Column10) VALUES
(:p1, :p2, :p3, :p4, :p5, :p6, :p7, :p8, :p9, :p10) ", items, transaction: transaction);
transaction.Commit();
}
private static IEnumerable<object> GetItems()
{
var list = new List<object>();
for (int i = 0; i < 200; i )
{
list.Add(new
{
p1 = new Random().Next(0,999999),
p2 = 1,
p3 = "-",
p4 = "--",
p5 = "--",
p6 = "---",
p7 = "----",
p8 = DateTime.Now,
p9 = "-",
p10 = 1
});
}
return list;
}

Your current code is not really doing a Bulk Insertion
. It insert once by once every item in your list
Learn about Array Binding insertion if you really want to do a BulkInsert
in Oracle with the fastest performance.

This project is not free but lets you easily do bulk insert in Oracle (use also Array Binding under the hood).
// Your mapping
DapperPlusManager.Entity<TEntity>().ToTable("TableName")
// ...code...
transaction.BulkInsert(items)
