Because we don't pregenerate an index. We don't even pregenerate a
metadata cache yet.
If you've got metadata pregenerated, inquisitio takes under a minute to
run, and it takes you much longer than that to read its output, visit
package homepages to see if they're what you want and so on.
We *could* generate an index, but then you'd have to keep it up to date
after every sync, which is sloooooooow. Or we could generate it
centrally, but then we'd run into the same problems that eix has: what
we have centrally isn't the same as what's on your local box.
