I've done some informal comparison between my LC475 and an aging 900MHz
AMD Duron laptop. The LC475 has a full 68040 at 25MHz, and the inter-
nal SCSI disk has been changed to a more recent one.
I've found that the Mac is roughly 100 times slower than the laptop
for CPU-bound operations, both integer and floating point. It is 50
times slower than the laptop when compiling -- but that's perhaps not
significative, the laptop has a different version of gcc.

24x is, if I'm not mistaken, roughly 4MB/s (probably less than that --
CD vendors lie). IIRC, that's roughly what I get from the LC's disk.
