I just discovered HHVM, a virtual machine designed to execute PHP (and a closely-related new language called Hack) much more efficiently than the standard PHP interpreter. Read about it at hhvm.com. (I think this started with an effort by Facebook to improve PHP's performance.)
The HHVM developers test its compatibility with popular packages including phpMyAdmin. They claim their latest tests show 99.85% compatibility, whatever that means.
Are the phpMyAdmin developers paying any attention to this effort? Should they?
