I've noticed, that IE calculates .length property of arrays by counting 
all array elements. This makes such cycles especially slow:

for (var i = 0; i < frm.elements.length; i++)

This can be easily fixed by assigning length to a variable:

var elements_length = frm.elements.length;
for (var i = 0; i < elements_length; i++)

You could search XSLTForms javascript code for ".length" and try if this 
fix makes it better.
