First you need to identify the bottle neck correctly. The
73/75/7600 computers run with a bus speed of 40 Mhz, and can move
about 10 M Bytes per second to/from memory. The real problem is USB
which only runs at 12 M Bits per second (1.2 M Bytes per second).
With a USB CD-RW, regardless of the system, the best you will be able
to run at is 4x burn rate. If speed is really important, look at
either a Firewire based CD-RW or a SCSI one.
