Performance Diagnosis Guide

Quick triage to identify the most likely performance bottleneck in an Isaac Sim or Isaac Lab workload. This skill does NOT require profiling tools — it uses only nvidia-smi, standard Linux utilities, and Kit config inspection.

For deeper analysis after triage, use the profiling and nsys-analyze skills.

Phase 1 — System Snapshot (no Isaac process needed)

Run these commands and check for red flags:

GPU Info

nvidia-smi -q | grep -E "Product Name|FB Memory Usage|GPU Current Temp|Performance State|Clocks Throttle|Driver Version|CUDA Version|PCIe Generation"
