If you didn't know, most Intel and AMD cpu's are vulnerable for Meltdown and/or Spectre.
My motto was always to make small fast PHP code without the overhead of big frameworks like Symphony, Laravel, Zend, Yii, etc. etc.
Also, we've tried to solve events/hooks management in a way that doesn't impact speed, like it does in WordPress.
Now Meltdown and/or Spectre could have a speed impact of 5% to 30% on a system depending on what is going on.
So this could potentially decrease speed of websites as well.
This morning we received a kernel patch against Meltdown and Spectre and i couldn't detect any speed issues.
This could be because our memory footprint is very low and also a few DB queries.
If someone could tell the impact of any other CMS/Framework i would like to know.
Server specs (Server OS / Apache / MySQL / PHP / DragonflyCMS):
Fedora 25 / Apache 2.4.27 / MariaDB 10.1.26 / PHP 7.1.10 / Mercurial

The big impact (outside of VM's) is to DB access. The pay-off from CPG-Nuke/Dragonfly reduced DB queries was the first thing I thought of.
