So I assume the i586 version is better for you --- unless GCC suddenly got a lot better at optimizing code. --------------enig610E2ECC92D96AD36FEE42E7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9fjMcACgkQqs4uOUlOuU9O4gCfYzyA8I3gdDczf4y15/cmXBXm YFQAnjI7YnUY3u40STYGjbfLpnhyK0en =xNI2 -----END PGP SIGNATURE----- --------------enig610E2ECC92D96AD36FEE42E7--
