The coverage I've read so far indicates that impact varies by workload, but databases are sometimes called out in particular as being more impacted, as Felipe notes. My opinion is that you should patch. You can always buy more hardware. In a virtual environment, if the impact is x% you can add x% more vCPUs fairly easily. I know that isn't a perfect solution; if you have batch reporting clients, if they run on a slower CPU then they won't perform as well as they did before, no matter how many other CPUs you have. Same goes for single-threaded database processes like 4GL servers. If the performance hit is significant, you might need to migrate to a beefier host to completely offset it. Another way to look at it: if your business grows, you will eventually outgrow the hardware you're on anyway. Applying these patches might just bring that day a bit closer. But not patching means you're rolling the dice.
