LOL yeah, um, no. ;-)

I can stand up a second VM and do the migration fairly easily. I’d rather not chance breaking the existing server.

hehe, I recommend you know what you are doing before trying that, there is a big chance that stuff will break and I will not run a support-line on the blog :p

But basically just add the repo from the blogpost and install the php7.0-packages, make sure to remove the php5 packages and make sure certain cronjobs that run specifc php5-stuff is removed like /etc/cron.d/php5

depending on what you use you might need som additional packes like php7.0-ldap and php7.0-gd.

“This is based on the Ubuntu 14-guide and assumes you have a freshly installed Ubuntu 14.”

Awww, no how-to for upgrade of an existing system without having to do a backup/restore type installation? ;-)

Good news everyone!

PHP7 is out and promise great performance to all PHP-applications.

I tried it out this weekend on my Observium-installation and it did not disappoint!

I have a rather large Observium and some of you that runs very large installations may have noticed that the web UI can get a little slow when rendering all the stuff from a large database.

In my case the overview-page loads in about 5s and some of the more heavy pages like /devices/ takes about 7s to load.

Well after upgrading to PHP7 my page loadtimes are now down to <1.5s for almost any page and atleast <2s for the heavy ones, I got a 2-3x performance boost!

If you want to try it out I made a quick guide on how to run Observium on PHP7 here: http://blog.best-practice.se/2015/12/vastly-improve-observium-performance.html

Note that I don't know if everything in Observium is fully compatible with PHP7, I tried as many features as I could think of with no problems, however I have not tried the billing-module.

Even if most of you don't have need for a speedup in the web UI, its great to see PHP improve performance like this.

This means Observium will be able to scale even further in the future :)
