i guess that until 3.5 or 3.6 the md5sum-application was really fast.
i was able to mark all my tcz-files and all md5sums were checked in an easy and fast procedure.
now in 3.7, but also in 3.8rc1 it is very slow to mark the tcz-files, after 5 marked files it takes some time until the system responses again... actually it makes no fun to check the files anymore.
i think this appeared in the same version, when the info-files were downloaded to the home-directory.
is it possible or makes it sense to get the previous system or behaviour back again!?
