If i upgrade to php 7 from 5.6 will it effects una? Is it safe?
I am running php 7.1 on mine and have upgraded from 5.6. You should be fine.
Did you felt change in Performance?
Runs honestly the same I think but some notice a little more performance.
Oh ! I'm disappointed, I thought the page would be displayed before clicking :-)I remember that someone had done a test with dolphin and said 7 times faster. But I guess it depends on the work requested ....
I wish. Unfortunately, that's unrealistic but it does look cool saying my site is running on 7 vs Old School but functional 5. Hahahaha
Yes, an upgrade from PHP 5.6 to 7.0 is safe and promising the better performance (see the tests between PHP versions). So the most proper way to compare - the installation of the Profiler App and the checking performance of the main pages. How to work with the Profiler App you may find here https://www.boonex.com/trac/dolphin/wiki/TutorialHowToCalculateLoadAndHardwareRequirements (there are no big changes between Dolphin / UNA in the using).
Which version of php 7 is ok for this?
Thank you Leonid, I have never been interested in profiler, I will do it.
7.0 and 7.1 versions are fine
BTW - PHP 7.2 is fine for the UNA from RC8 version.
