I found in my second pass at K3b that it is possible to use some parts
of it separately. For instance, when you give it the name of a disk
image file, it will go off and calculate the
MD5 sum whether you want it or not. This takes long enough to be
timed with a stopwatch. (1:35 to read and compute).
Likewise, you can use K3b to perform the single function of "create a
disk image on hard drive by reading from CD drive". This too can be
timed with a stopwatch at 3:30. I assume this is the amout of time
it takes to read the from the CD drive, and writing to the hard drive
is insignificant.
But using what are presumably these program parts in the orchestrated
K3b fuction "create a CD from an image on hard drive, calculate the
md5sum of the original image, calculate the md5sum of the created CD"
takes 20 minutes each for the two (read and calculate MD5) parts.
Timed with a stopwatch, or with K3B's elapsed time readout.

I compare these with similar operations using standard programs md5um
and dd, and get times of 0:45 and 2:40 respectively.
