My typical results using both (on a not-so-hot laptop):

# time /usr/bin/gtk-update-icon-cache --force /usr/share/icons/hicolor
Cache file created successfully.

real    0m0.637s
user    0m0.492s
sys     0m0.145s

# time /usr/bin/xdg-icon-resource forceupdate --theme hicolor
real    0m0.657s
user    0m0.491s
sys     0m0.166s

Not nearly as big a difference as your findings.
