foreach not rendering as quickly as it could #59

I have a coworker that's always going on about how backbone is god's gift, and that I'm retarded for using knockout. Today, he sent me this: http://fiddle.jshell.net/ntMdB/139/

it's not apples-to-apples because he's using knockout to setup a bunch of two-way bindings for a one-way view. So I modified it so that the only thing observable is the array. But the only way I could get it to render any faster is to mess with the item order. http://fiddle.jshell.net/ntMdB/151/

if i do an array.reverse, it's the same speed as his: http://fiddle.jshell.net/ntMdB/157/

How can I get the speed of 151 with the same rendering result of 139 and 157?

This is actually related to Knockout itself, not the mapping plugin. Feel free to open an issue there. Having said that, the new release is already quite a bit faster than when you originally opened this issue :)
