Oracle Application Express (formerly HTML DB) - Version and later
Information in this document applies to any platform.


When loading 250,000 records from a CSV file using Apex "Data Load" utility, it takes 10 minutes just to load the file into apex to display the data / table mapping page.  The target table is empty,  no indexes on target table, just a primary key. Not performing any look ups, transformation, or concurrency.  This is a very simple load.  There are zero processes or pl/sql calls.  Not doing any customizations.
