I have done some new benchmarks of WordPress with a page caching plugin.
This time HPHP gave even more impressive results.
With a page caching plugin, HPHPed WordPress has gained 2.7x speedup over
PHP. Dynamic page generation of HPHP is super fast that its speed is more
than a quarter of static content by Nginx.
