Description

Periodically reading cgroup stat data can be expensive across a large enough fleet. I will discuss work done this year that focused on optimizations in this area and provide some background on the data/rationale that led us there. The presentation will include one technique for avoiding the expensive conversion/formatting involved with reading memory cgroups.
