It has gotten a lot slower over the last few months: it used to take 2
or 3 seconds (provided that all the Nix expressions where in the disk
cache - all the seek times for those small files add up), but now it's
more like 10. This is probably because some expensive computations are
being done in Nix expressions (like the uniqList function) which might
be done in a different way or turned into primops.
So we should do some profiling...
Yes please :) nix-env -qa something takes ages, too :(
