Wordpress and MediaWiki are both written in PHP. But this level of 
scaling doesn't require a framework that scales. It requires a database 
system that scales, a clever load balancer, and an RPC mechanism.

There are several popular forum systems written in PHP, and they are 
sometimes required to scale a fair bit on a single host. I'm seeing few 
concrete references in terms of QPS, but it looks like, for phpBB, people 
are recommending splitting frontend servers from database servers around 
1500 simultaneous users.

Another way to estimate (crudely) how well platforms scale is to compare 
pricing for similar products implemented in each. vBulletin, for 
instance, has a $75/month tier supporting up to 200GB of data transfer. 
nodeBB has a $100/month tier supporting 500,000 monthly pageviews. These 
turn out to be roughly comparable if you ignore caching, and nodeBB has 
some extra value adds. So vBulletin and nodeBB probably scale similarly 
-- unless one of these organizations is getting significantly different 
profit margins or something, anyway. And this is evidence toward PHP 
scaling about as well as Node.js.

Collating a large number of examples like this would give us a good 
overall estimate of each platform's scaling properties.
