10 There is some progress here. In portage-2.2.15 profile based
11 optimizations are included (see bugs 529660, 530010). On my
12 hardware (Athlon-XP, 2200 MHz and Intel Atom N270, 1600 MHz) they
13 speed up dependency resolution by ~ factor 2.

15 Of course it will be great to see further optimizations, though as
16 far as I remember this will require more complicated changes.
