A note on performance impact;

I patched this debian webserver yesterday at 08.30 with the meltdown fix. Admittedly it is a lightly used VM. The small spike in these graphs is for that reboot. The larger evening spike for the daily backups.

I cannot see *any* difference in load or cpu usage in this single real-world example from applying the patch. (The weekly graphs show no relevant change against previous days either)
