It seems possible that there's something badly misconfigured about the disks on your new machine. Benchmarking with "bonnie" or some such would be useful; also try looking at "iostat 1" output while running the inserts on both machines. Also, are the inserts just trivial "insert values (... some constants ...)" or is there more to it than that? regards, tom lane
