Databases are fast at INSERTs! 1¼ minutes to insert 1¼ million rows (on a test server!)
From our Oracle test instance at uboot.com:
1360965 rows created. Elapsed: 00:01:17.90
That's 1¼ minutes to insert (and index) over 1¼ million rows.
And this is a very old test instance. I think the hardware was last updated 2-3 years ago.
That's pretty quick!
