Serious performance issue with "foreach" in native template engine, can take 3 to 5 seconds on a simple couple of hundred row table just to display, scroll down the click the sort button and watch how long this trivial example takes:

We are working with a very large client doing a rewrite with KO and this is turning out to be show stopper, 3 to 5 seconds to layout a 200 row table is far to slow to use.
