I did not calculate the IO behavior of the server.
What i noticed for the logs is that, the checkpoints are occurring too frequently each checkpoint is taking up to minimum 80 - 200+ seconds to complete write and checkpoint sync is taking 80 - 200+ seconds to sync, which is i believe IO intensive.
Thanks

just ruling out something obvious -- this is vanilla create table, not CREATE TABLE AS SELECT...?
also, what's i/o wait -- are you sure your not i/o bound and waiting on transaction commit?
