HHVM (also known as the HipHop Virtual Machine) is a virtual machine for PHP, with an associated just-in-time (JIT) compiler. Deploying HHVM on a MediaWiki wiki should lead to performance improvements across the board for most users.
HHVM was fully deployed to all wikis on 2014-11-25.[1] You can verify that it is enabled for you by visiting Special:Version on your wiki, and checking that it says "HHVM" instead of "PHP" in the "Installed software" table.
Our preliminary benchmarks[2] show that HHVM is significantly faster than the current PHP interpreter.
