-TL;DR: Smarty is slower than Twig, Twig is faster than Smarty. Don't trust benchmarks from years ago.

 ## Opinionated How?

     XSS trouble.
   * Doing a benchmark that _disables auto-escaping_ can hide performance problems in a part of the template engine you
     *definitely* want to be using.
-* This test is being performed in 2017, which means we're not even going to bother with PHP5
-  * A *lot* of things are different in PHP now, for example, objects have better performance characteristics in PHP 5.4+ (https://gist.github.com/nikic/5015323)

-Most other benchmarks I've seen date from around 2011 or 2012. That's ancient in web-development terms. And unfortunately,
-I've seen a few PHP coders get caught out, choose Smarty because "it's faster" (or so says one benchmark), and end up without
-escaping throughout their templates.

-Yes, authors should probably know to escape their output. But, equally, a single oversight shouldn't result in a vulnerability.
 
 ## Templates
