I just profiled on of my pages today and s:selectItems can indeed be a problem
for combo-boxes with many entries.
The code below is from asSelectItems() in UISelectItems.java:
| for (Object o : iterable)
| {
| initVar(o);
| selectItems.add(new javax.faces.model.SelectItem(o, getLabel() ==
null ? null : getLabel(), "", getDisabled() == null ? false : getDisabled()));
| destroyVar();
| }

As you can see getLabel() and getDisabled() (usually value expressions) are
called twice per entry. I've changed this locally to use local variables and it
makes a noticeable difference.
In my case there are even more combo box entries - your mileage may vary ...
Thanks,
Stephan
