What is SSL and do I need it?

PHP 7 has finally been released and the performance boost offered is simply unheardof!  At least according to the founder of the PHP scripting language, 100-percent-plus performance improvements have been seen in version 7. The new version features engine improvements, lower memory usage, and native local thread storage.

But do you need it?

The biggest reason for upgrading to PHP 7 is it’s performance, brought primarily with the changes introduced as phpng. As things currently stand, depending on whose benchmark you see, the performance of PHP 7 is on par with Facebook’s HHVM, which features a Just In Time (JIT) compiler that compiles PHP code all the way down to machine instructions (if it is able).  Unfortunately, PHP 7 does not feature a JIT, though it has been discussed a lot. It is unclear if there are more performance gains to be had with the addition of one, but it sure will be interesting to see if someone decides to create one!

In addition to performance, there should be substantial memory savings for VPS and dedicated server users, as optimization of internal data structures is one of the primary ways in which performance improvements have been achieved.

WordPress and Drupal users will definitely see performance improvement, as more clients can access their websites in shared hosting, thus reducing the need to transfer to a VPS or switch to a dedicated server.

PHP 7 is available to our shared hosting customers, while our VPS and dedicated server customers who use Plesk for their control panel can get the update simply by updating to Plesk 12.5 and installing the latest microupdate.
