Just to follow up on the original post, I did take a look at
the results, and went as far as establishing that in most situations,
the reverse lookup cache appears to have a very high hit rate,
indicating that it is not the bottleneck. The rspl reverse lookup
statistics don't seem to give any hint as to why the gamut mapped
performance is worse than three times slower than the un-gamut
mapped one. Without a lot of digging around, the performance
slowdown remains a bit of a mystery.
