Very slow ripping

With hdparm set as follows
/dev/hdc:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
I'm occasionally getting better read speeds -- for instance,
right now I'm ripping at something like 3.3x -- but
certainly not up to the 24x capacity of the drive. The CPU
is hardly taxed at all -- the GNOME meter shows it somewhere
around 25%. Periodically I get rip-speed spikes up to the 4x
range. On the other side of the apartment is a desktop
machine equipped with two CD-ROM drives, each of which gets
up to 8x regularly. What do you think its secret is? (I
don't have sudo access on that machine, so I can't install
hdparm there.)
