HHVM joins the Bitnami Library!

We are happy to announce that the Bitnami HHVM Stack is now available on our Bitnami Library. HHVM is an open-source virtual machine that is able to execute PHP programs, in addition to its own programming language, Hack. It has been developed since it's origins by Facebook and is said to be a competitor with PHP itself. With that in mind, a large number of PHP applications are working to become compatible with HHVM.

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 installersVirtual Machine images (VMs), and cloud images.

We cannot wait to hear your thoughts about this stack, and we invite you to leave your comments and reviews on our stack page.

You can find more information about how to manage your installation on our wiki. Still have questions? We would be happy to answer them on our community forum.
