We have just released our new technical explainer video: “Kernel Theft on ARM64/Linux? ASP Finds the Bottleneck (Not Your Code)”.
(And it is in a new format that we are working on. Let us know if you like it better.)
In this video, we deep dive into the Ampere System Profiler (ASP) and our top-down investigative methodology for performance tuning. We tackle the frustrating problem of “kernel theft”—where your dashboard shows high CPU utilization, but your application throughput remains stagnant because the system is bogged down by kernel-level tasks.
What you’ll see in the video:
- The “System Microscope”: How ASP provides a high-level “first-pass” report on system health (CPU, Disk I/O, Network, and Power) before you ever need to dive into complex microarchitectural analysis.
- The Redis Case Study: A real-world walkthrough of how ASP acted as the “star of the debug,” solving an unexplained 60% performance regression by uncovering hidden network IRQ configuration differences.
- Live Demo: A quick guide to cloning the repo and setting up the tool on major Linux distributions like Ubuntu, Fedora, and Debian.
