Re: good pc but bad performance,why?

Hello, Richard Huxton,

         You said  turning fsync off may cause losing data, that's terrible.
    I use SCSI disk, and file system is ext3. I tune postgresql.conf and can't get any improvement. So what can I do?
    Does SCSI disk and IDE disk have difference?

         Regards,
            Huang yaqin
