HHVM

What do you like best?

HHVM is an open source project for compiling programs written in PHP. I like it because HHVM compiles the PHP in an intermediate bytecode instead of interpreting the code directly. Then this bytecode can be easily run on any 64 bit machine using a JIT compiler and provide high performance for my PHP programs. The best part is it is backed by software giant Facebook and has extensive community support from them. It is best suited for websites getting lots of requests in a short amount of time.

What do you dislike?

The very first disadvantage is for the 32 bit machine users; they can use it as it doesn't support 32bit OS machines and runs only on high end machines. I also observed that not all WordPress plugins are supported by it. Rest everything looks good from a developer perspective.

Recommendations to others considering the product:

HVVM is a very good option if you are looking for high delivery speed for the user experience.

What problems are you solving with the product? What benefits have you realized?

The benefit of using HHVM is any website can have dynamic translation which makes the page load faster in required situations. Moreover, static typing improves the overall compilation speed and uses very little memory space for executing the requests. It is open source, so anyone can use it without paying for the installation or configuration.

To add further, WordPress websites uses very less CPU resources when linked with HHVM and thus can take up more number of transactions per second to generate large concurrent requests submitted by users.
