I used wc to shorten the output; the package list is the same in both
cases, except my version also shows and matches version numbers.

dmcgee at dublin /tmp
$ time ./repopkg.orig testing | wc -l
28

real	0m13.195s
user	0m9.166s
sys	0m3.343s

dmcgee at dublin /tmp
$ time ./repopkg testing | wc -l
28

real	0m6.445s
user	0m4.523s
sys	0m1.203s

The magic:

pkglist=$(mktemp)
pacman -Sl $1 > $pkglist

pacman -Q | while read pkg; do
  ret=0
  grep -q "$pkg" $pkglist || ret=$?
  if [ $ret -eq 0 ]; then
    echo $pkg
  fi
done

rm $pkglist

And sample output:
