it takes only about 1/4 more time to kill creatures in hard mode 50 cap, and about 1/2 more time in level 25 cap.
(which is also the case in DOS, Hard mode just cuts all of soma's attributes in half and changes a few of the minor enemies, yet of course, it's not part of PoR, so apparently it is to be spared from the same critism it deserves)
the only case in which this bias actually applies IS on level 1 cap with a fresh file, so I don't think I'll ever bother doing that with a fresh file on any mode except the sisters. using the save file glitch with richter mode (giving you the life and magic upgrades) though makes it pretty fun.
