I have a new maxtor 8.4GB UDMA drive (88400D8) on an ASUS TXP4 mothboard. The disk is twice as slow under udma as it is under pio. From a fresh boot (so there is nothing in the caache I hope) it takes 16 seconds to start emacs under udma, and 8 seconds for the same operation using pio. My laptop, which also uses pio, also starts in 8 seconds.
Shouldn't udma be faster? And what is broken for drives greater than 8GB?
