And this is a problem because...  ?

Honestly, you're doing a lot of work, why wouldn't the CPU be busy?

Are you using COPY or a series of INSERTs?  If the latter, are you
doing them all inside a transaction?  INSERTs not wrapped in a
transaction will load the system a lot more due to transaction
overhead and disk sync latency.
