When the Oracle connection has been configured as a Direct connection, the import wizard of big Excel files do the process every 5-7 rows.
- The Oracle client (OCI) connection has better performance than the Oracle Direct connection.
- Option Optimize the block size has been selected.
WORKAROUND 1:

WORKAROUND 2:
When working with Direct connections to the Oracle databases, create the connection using an Oracle client.
