What do you do, if after you upgrade / patch, you realize you have a performance problem on your VMS? Replace the CPU? Replace the server? What are one's practical options?

Why are these exploits even an issue in a closed environment such as a VMS server? No one is going to be using one to surf the net or adding random apps, or am I missing something?

Forgive my low reading comprehension but am I understanding this right? I'm hoping what is meant is that if we're at 10% load it is jumping to 18%-19%.

The problem right now with BIOS updates is Intel released code that is causing a reboot problem. Dell, HP, and Lenovo have all removed the latest BIOS patches from their downloads and are recommending anyone who installed them to roll back. If you recently patched your BIOS, you should go back and check to be sure you didn't install a version that has been retracted.

Purely from a testing methodology standpoint, was testing done with Milestone Smart Client hardware acceleration enabled? It could stand to reason CPU usage and impact would be less than this if GPUs would being used to decode and render...

Don't suppose you can build an AMD Ryzen machine and retest this?
Intel has done a great job convincing everyone that Meltdown affects everyone despite AMD being entirely unaffected by this. So I'd be super curious to find out how much the Meltdown patch affects the speed vs Spectre.

We are currently evaluating this situation and discussing with customers whether or not to actually applying the BIOS patches.
The reason for this is that we want the customers to have a choice. Many of our customers have distinctly disconnected networks for CCTV and very high control over what can be installed on their machines, like web browsers.
To do this we need to call on our corporate security experts to look at the attack vectors and recommend actions.
With these high impacts we are seeing, many of our customers will have to do expensive and time consuming upgrades if there is no way around the BIOS patches.

This BIOS vulnerability, can it affect dedicated Linux OS recorders/NVR's with Intel chips or only Windows/Intel devices?
How about the Meltdown vulnerability on these same devices?

To my reading and understanding, this is a bit hyped... sure it's serious bug, when you have someone or something executing on your host.

I tried to reproduce it myself.
Realized that my NUC (nuc7i3bnh) doesn't have Meltdown/Spectre fix available on the Intel website (latest Bios update is Nov 2017).
Tried to find your firmware (RYBDWi35.86A.0368.2017.1220.0950) and failed again.
The only link from Google leads to 404 https://downloadmirror.intel.com/27426/eng/RY_0368_ReleaseNotes.pdf
If check downloads for your model (NUC5i7RYH)
https://downloadcenter.intel.com/product/87570/Intel-NUC-Kit-NUC5i7RYH
the latest Bios update is dated September 2017.
Looks like Intel takes down the Bios updates as there is too many issues with the upgrade.
