Fast way of sorting VLayout members

SmartClient Version: v8.3_2012-11-20/LGPL Development Only (built 2012-11-20)
FF 25.0

I am trying to display a list of 100+ objects in a VLayout and sorting them on-the-fly afterwards.

I have tried both setMembers() and reorderMember() on VLayout, but the performance is very poor (> 5sec).

The only reordering method that seems to be fast is setReverseOrder() followed by reflow(), but that of course only works for reverting the order, not for sorting.

Is there some faster way of sorting layout members ?

Kind Regards,
Jan
