a freelancer wouldn't know and if they did they wouldn't care. (i am a freelancer.)
we're talking about websites that are in the top 5% of all sites (by traffic) that would even need to think about using something like phpc or hphp. the number of those that would be willing to use a freelancer to handle their scaling issues are probably in the single digits at best.
On a tangent, I wonder why lots of people call it something other than "phc". I said phc a lot, its on the website as phc, but I've heard phpc, phpcompiler, and tons of variations. I'm curious why.
