When CPUs Hide GPU Bottlenecks: How Btune 2.0 Automates Latency Analysis to Uncover Performance Issues

The article presents a real‑world migration case where a CPU‑XPU bottleneck limited inference QPS, explains how Btune 2.0’s new latency‑focused diagnostics pinpointed a kernel lock contention in the halolet component, and shows the AI Agent’s automated, cross‑process analysis that restored performance and reduced cost.
