[gentoo-portage-dev] trying to speed up emerge

[Joakim Tjernlund]

emerge -NDuv world takes a log time until it begins to build pks, has been
like this for a long time.

straced emerge and I see the pattern below repeat over and over again.
I figured there is some cache problem but I cannot find out how to fix it.
Been running emerge --regen/--metadata and egencache --update --repo xxx for all repos/overlays
Where to look next?
