Punters said that, since AWS began rolling out anti-Meltdown updates in December, they have noticed an increase in CPU utilization by their EC2 virtual machines. The solution is to either optimize the application code, or move to a more powerful and expensive host server to take the extra load.

"Immediately following the reboot my server running on this instance started to suffer from CPU stress," one admin noted after installing the patch.

So (obviously) Intel's statement that patches will barely have any noticeable performance penalty was pretty much fake news. It was already clear the moment Intel released the propaganda statement.
