HHVM and MongoDB — the perfect combination
summary
An HHVM extension for MongoDB exists that mimics the PHP extension API, backed by a C driver for connection and BSON handling, plus a composer-ready PHP library on top that reimplements the old driver API. The PHP-layer code runs nearly the same speed as C++, benchmarks show ~25% faster for HHVM versus PHP5 and comparable to PHP7; builds work but HHVM extension development has hard-to-debug crashes, long compile times and a lingering memory issue that slows some test runs.
