Some applications run faster in 64-bit mode, because they make good use of the additional free registers... This is particularly important for crypto-stuff (it's noticeable even without benchmarking), and in some multimedia applications as well. And just to wit: some register-hungry applications run even faster on an old UltraSparc IIIi 1500 Mhz despite its slow memory than on a Phenom with 2.4 GHz and fast DDR 3 RAM. So it all depends on the particular applications. -cpghost. -- Cordula's Web. http://www.cordula.ws/ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
