I admit my way of putting it was blunt, and probably not exact. As you
rightfully pointed out, you were the first to raise the speed issue,
heck,
I think our save benchmark still uses some code of yours!

What I meant to say was: currently, syncing 300 or so contacts from my
MFE
account takes more than 80 seconds. So something can be improved
somewhere.
I have been meaning to spend some time on looking into this, but
haven't
done it so far. Maybe it is just the server that is slow, maybe we do
things
wrong, maybe you can batch more contacts together... Who knows! And in
any
case, we'll never be able to store 120k contacts in a reasonable time.

And about the "we're closed source": I hardly see how I could hold your
team
accountable for this, since this decision most likely belongs to Nokia
legal.
