You are right, a generic service like akonadi has to do a lot of work,
but it seems to have some fundamental design flaws, since it is 5 years
old and, in my opinion, still far away to be called "production ready"

Right, but it seems still to be way too lower. Moreover, with todays
systems, this seems to be very low anyway, also given how akonadi
depend on the custom copy of mysql.

Sometime the route "let's throw everything away and start from scratch"
is a better solution than "let's try fix all the probems" simply
becacuse you already know all the problems you will
have and can design the system with them in mind, instead of trying to
find a workaround in a flawed design.
