Certainly no problem when I visited Cape Town, sure no where near as busy as a major US or European airport but still impressive viewed from an old PA28-151.
Had to orbit downwind to let an MD80 in then a steeper than normal approach to avoid the wake, landing half way down the runway to clear quickly to let a 747 off. I'm sure his clearance was “after the PA28, line up” I wish I had been on tower freq rather than approach to hear it.
