Just a couple more data points, on my machine, with:

CPU : Intel(R) Core(TM) i7-6850K CPU @ 3.60GHz
SSD : Crucial MX200 1 TB SATA

And a hot cache:

$ time equery -Cq b /usr/bin/equery
app-portage/gentoolkit-0.4.0
dev-lang/python-exec-2.4.5

real    0m6.655s
user    0m6.462s
sys     0m0.193s

$ time equery  b /usr/bin/equery
 * Searching for /usr/bin/equery ...
app-portage/gentoolkit-0.4.0 (/usr/bin/equery ->
../lib/python-exec/python-exec2)
dev-lang/python-exec-2.4.5 (/usr/lib/python-exec/python-exec2)

real    0m6.598s
user    0m6.439s
sys     0m0.160s

$ time portageq owners / /usr/bin/portageq
sys-apps/portage-2.3.11
        /usr/bin/portageq

real    0m1.391s
user    0m1.348s
sys     0m0.044s

$ time qfile /usr/bin/qfile
app-portage/portage-utils (/usr/bin/qfile)

real    0m0.104s
user    0m0.085s
sys     0m0.019s


I think we have a winner here... qfile even takes the same -C and -q
options as equery.
