The test is almost same as I did before on php 5.5, php5.4 and php5.3, or php-fpm. It is running on the HHVM and Nginx.
The installation of Ubuntu 14.04, Nginx, MariaDB, HHVM is posted yesterday.
Using default HHVM settings. The HHVM is version 3.5.0, Nginx is v1.6.2.

It took more time than any other php version. I am confused and try to repeat the test, by refreshing the page.
The first ten times, are all around 5.8 seconds. Lower 5.788, higher 6.162. The eleventh gave me a shot, it is only 1.44 seconds. I kept refresh the page and saw similar results, around 1.4 seconds.

It is so fast.
I did a research and found the reason of first slow ten is for warmup. It can be changed to zero.
OK, modify the /etc/hhvm/server.ini , add following in the end.
hhvm.jit_profile_interp_requests = 0
Restart HHVM and done.
The HHVM will do the JIT from the first run.
