Thanks for the response.

It is, but I'm not sure my test rigging was correct.  Today, it looks
like the BTreeFolder2._setOb() is taking the time but the 
tree[id]=object line is not responsible.  Instead the 
object.manage_afterAdd(object, self) call seems to be the slowdown.

I was able to work around the problem by replacing
with my own version for this special case.

Thanks, I'll try that.
