My understanding is the patch removed certain branch prediction optimizations. Systems post-patch were running some loads at 30% higher usage. I don’t see how a reboot would affect that?
It reduced capacity by 30% which means a 40% increase in cpu usage. Here is one of my teams RDS instances during the timeline of the patch: https://imgur.com/a/khGxU
Exactly. That’s what I was suggesting originally. It seems pretty cut and dry and would certainly explain the abnormally large increase in cloud revenue.
This is ongoing, correct? Since fundamentally the patch disables optimizations that would reduce cpu workload for many tasks?
