Facebook Speeds Development With “HipHop Virtual Machine”, A 60% Faster PHP Executor

"Consider that many Facebook engineers spend their days developing PHP code in an endless edit-reload-debug cycle. The difference between 8-second and 5-second reloads due to switching from HipHop interpreter to the HipHop Virtual Machine makes a big difference to productivity." That's how Facebook explains the significance of its new PHP executor, HipHop Virtual Machine, announced today. It's 60 percent faster than the HipHop interpreter Facebook currently uses, with a 90 percent reduction in memory cost. HHVM will improve the performance of Facebook's code and speed up the development process without forcing Facebook to switch off of PHP, which its engineers are trained in.
