Are each of the INSERTs in their own transaction?

If so, you'll be limited by the speed of the disk the WAL is running on.

That means you have two main options:
1. Have multiple connections inserting simultaneously.
2. Batch your inserts together, from 10 to 10,000 per transaction.

Are either of those possible?
