oflag=sync is terrible and should never be used as it does the equivalent of fsync() after every single write(). Not only does this cause terrible performance, but in the case of flash, will wear it out much more. Use conv=fsync instead to fsync() once, at the end. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJUxnAFAAoJENRVrw2cjl5RsAoH/j04e1KNeZ/HBaxOH7psm/oB XkV+yWiEMZD0nGp61YX03z+y/8LCSpIrzFL14bQMoQm5llrJ8cACjZk3wBn1zKfp XzPKdW02/ve9EjNjo3vdvUj+gApneImodVqsnvIuxJUarkJzTYb7ogXLWNEImgjv B9UEPXKqKFsiVmyojLhUFKhhUxgIUkB09aqNhir3N+cYs/y79DBsg2n3RF6AKSb2 47TzwIAX4LKNOBUB0XLiUOsmQ5D8HhYxIaXpmtQ7qM+UzUAVponBmBK/Dy4MgsOW OH132E4vddSHh9se/3YnAj7CfgM+xwftcG1IElMykiKr74pblc3mKHqC5KveO68= =Xwy4 -----END PGP SIGNATURE----- -- ubuntu-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel
