See bug 914255 comment 11.

I believe we have typesets up to 17 in size or so in these tests.
Summary: Significant DOM traversal performance regression from limiting typeset size → Significant (15-25%) DOM traversal performance regression from limiting typeset size
I will probably just backout. It's unfortunate, since that will give us more recompiles. Like suggested in comment 11, there is probably need for a DOM (sub) type. That way we can still do the DOM optimizations even when lowering the number tracked types...
