- 4The New Stack·9/27/2026researchAdrian Cockcroft on performance engineering from kernel analysis to AI tools
The article highlights Adrian Cockcroft’s long career in performance engineering and his evolving approach to finding system bottlenecks, from reading kernel source code to using AI-assisted "vibe coding" to build custom analysis tools. It also argues that percentiles like P99 can hide important latency patterns, especially when response-time distributions have multiple peaks.
- 5InfoQ·9/23/2026open_sourceGoogle Adds Cycle-Level Kernel Profiling to XProf
Google has added a Kernel Profiling suite to XProf, its open-source profiler for TPU workloads. The update lets developers inspect cycle-level behavior inside custom Pallas kernels, which previously appeared as opaque blocks in trace captures.
