We found that malloc() was called _very_ often during widget creates
(I'm talking about the HP widgets, but I guess the same applies). It
is well worth shopping around for a fast malloc. Last time I looked
the malloc() in Gnu was about twice the speed of that in libc.a (HPUX 6.5)

The other thing that made a big difference to us was creating all a widget's
children with XtCreateWidget() and then doing a XtManageChildren on
the whole batch.
