The Bitnami HHVM Stack includes HHVM along with Apache, MySQL and PHP, so you will be able to switch between both engines and compare them.
As an example, we have configured WordPress on top of HHVM and ran some tests facing our WordPress cloud images running PHP-FPM 5.6. One of the conclusion that we came to is that HHVM allows about 170% concurrent users versus PHP-FPM 5.6, which is a significant advantage.
The following tests show the results of running a T2 AWS micro instance with WordPress configured with PHP-FPM v5.6 and HHVM v3.6.5. The first test shows that with the PHP-FPM configuration the users start getting timeout errors when there are 42 concurrent users in the server. The second one shows that WordPress configured with HHVM could serve the requests without timeout errors until the server has 80 concurrent users.
Get HHVM running in just a few clicks with the Bitnami HHVM Stack installers, Virtual Machine images (VMs), and cloud images.
