That's less than 1/2 the speed of my Athlon 4850e (2.5GHz) and only 60% more than my Atom N270. None of the other figures you posted look anomolous. Are you sure the CPU is actually running at full speed and you haven't done something like disable the caches in BIOS? --=20 Peter Jeremy --r5Pyd7+fXNt84Ff3 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAkyZum4ACgkQ/opHv/APuIfbZgCfZQ1nUw1+dMSlGdmU6zHOIlCI KnUAniULSbKXJRcyWejXdCcWPVk85fN7 =MSiL -----END PGP SIGNATURE----- --r5Pyd7+fXNt84Ff3--
