Understanding whether a process is truly starved of CPU time isn’t as simple as looking at traditional metrics like CPU usage or Load Average. Few realize that the Linux kernel has built-in mechanisms to precisely measure how long each task waits for kernel resources. This talk delves into delay accounting, an often-overlooked feature that provides valuable insights into CPU time shortages and application latency. Attendees will learn how to leverage these kernel metrics for better performance analysis and system optimization.
