Axiom Performance Profiling

charleswiltgen/axiom
197 installs1.1k stars
Summary

This is a comprehensive router for diagnosing any performance issue in iOS apps. It covers the full spectrum: memory leaks and retain cycles, CPU profiling with Instruments or xctrace, app launch optimization, battery drain, hang diagnostics, and Swift-specific performance patterns. The decision tree is genuinely helpful because performance problems often look alike at first glance. If your app feels slow, this gets you to the right sub-skill fast, whether that's Time Profiler for general lag, hang-diagnostics for UI freezes, or app-launch for cold start regression. It also routes to automated agents for proactive scans (memory-auditor, energy-auditor) and includes practical escape hatches like timer crash patterns and LLDB debugging when profiling alone isn't enough.

hyperpod-performance-debugger

awslabs/agent-plugins

Diagnose performance issues on Amazon SageMaker HyperPod clusters — uneven NCCL bandwidth across nodes and poor filesystem throughput. Read-only. Surfaces host-side signals (Xid, ECC, NVLink, EFA reachability, FSx saturation) and routes to the appropriate sibling skill (hyperpod-node-debugger, hyperpod-nccl, hyperpod-version-checker, hyperpod-issue-report) for any remediation. Triggers on uneven NCCL across nodes, straggler node, FSx slow, checkpoint slow, dataloader slow, filesystem bottleneck, FSx throughput, cross-AZ latency, topology mismatch.
