The filesystems have a 4k block size, so the default of 512 is dead slow, but once you hit the block size the improvments stop. I usually use dcfldd these days, which seems to do a good job of working out the optimum block size for itself, instead of using a prehistoric default. --=20 Neil Bothwick Anything worth fighting for is worth fighting dirty for. --Sig_/Kt_==dExGOcf5BG4nH+_UxM Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlQERo8ACgkQum4al0N1GQM3ZgCeOvcY/vGybw4XMt2t6gy7qrGz ui0AoMrwjyzjUi4wGuIBmSilyXQl2ust =JRor -----END PGP SIGNATURE----- --Sig_/Kt_==dExGOcf5BG4nH+_UxM--
