--- Comment #2 from Markus Mohrhard <markus.mohrhard at googlemail.com> ---
Do you have a callgrind log for such a case? Normally all cases that I have
seen can be somewhat reworked to make better use of the new data storage as it
is quite difficult to produce a test document that accesses a huge amount of
cells in an unstructured way.

It might not be always trivial to find the place that is actually looping as
there are quite often several layers of indirection. Through these indirections
cell access might appear to be random instead of being structured.
