At a hint from Marti that he has added a special case for matrix
only profiles, I've repeated the benchmark using lcms V2.0.

Matrix profiles:

lcms    73
argyll  65
qcms    32

cLUT profiles:

lcms   357
argyll  69
qcms   n/a

So for the special case that only qcms supports, lcms V2 is just as fast as 
and a factor of 2 slower than qcms. Whether this is significant in practice for
use in a browser probably depends more on whether color management is
being applied efficiently, or whether it is being applied badly
(Consider: even a large display only has around 4 Million pixels, so
repainting the whole screen should take about 15msec's worth of color
