It's hard to do a fair comparison. I'm rendering the Mustache template using the IJSONRequestCache data (which is the same as we'd use on the client side). If you look purely at time-to-render, it's not fair to include the IJSONRequestCache retrieval and Mustache is slower. But if you assume that we are going to want to populate the IJSONRequestCache anyway, then Mustache wins because it doesn't need to re-retrieve the data. However, that's due to the way we're using TAL, and I believe we could use our Mustache strategy with TAL, i.e. use the IJSONRequestCache as TAL's data source. Also, Mustache template uses our new design, so the HTML is not identical to the TAL. Here are the times for retrieving 100 requests sequentially using wget: TAL with populated IJSONRequestCache: real 0m26.908s user 0m1.256s sys 0m0.524s variation: ~300 ms TAL with no IJSONRequestCache: real 0m22.481s user 0m1.224s sys 0m0.760s variation: ~500 ms Mustache (using IJSONRequestCache): real 0m25.917s user 0m1.208s sys 0m0.772s variation: ~700 ms Of course, technically, we could skip the server-side rendering :-) real 0m25.639s user 0m1.232s sys 0m0.660s I don't see great risk with using Mustache, but we should always test performance when we make big changes to the way a page is rendered.
