My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. Our team looks after the BaseAMI, kernel tuning, OS performance tools and profilers, and self-service tools like Vector. Not a lot has changed with these tunables since my [2014] talk.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. We ended up setting it in the BaseAMI for all cloud services. How long does it take to read the time? How would you _time_ time?

Xen's biggest user is the Amazon EC2 cloud, which has over one million customers, and appears to be a custom version (it self identifies as version "3.4.3.amazon"). Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less).
