Thomas, could you please try with the following patch and let me know how much
faster it is for you then. It disabled Nepomuk access in the message list,
which gives me a 3x speedup without having Nepomuk running at all, so likely
more if there has been a working Nepomuk before. This is of course not the
solution to this problem, but would indicate that I'm looking in the right
direction to fix this, since I cannot confirm the numbers posted here on my
system, loading 10k messages takes only ~2.5sec here.
