It is hard to give advice on what you could do differently if you don't
tell us what you do.
How are you inserting those rows?
How are you creating the indexes?
Especially: Are you doing things serially or in parallel?
Also performance depends a lot on hardware, so faster CPUs (or more
cores) and faster disks/ssds might help, too.
