HHVM/About/sv

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.

Currently, on Wikimedia wikis, you can opt-in as an editor to using HHVM through the Beta Features tab in your preferences. 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. Once the developers and sysadmins are satisfied that it is stable enough, it will become the default for all users.

Our preliminary benchmarks show that HHVM is significantly faster than the current PHP interpreter.
