Latency Tracker Per-call and aggregated latency tracking for MEV infrastructure. When to Use - Implementing performance monitoring - Debugging slow operations - Adding instrumentation to code paths - Tracking end-to-end latency - Setting up alerting thresholds Workflow Step 1: Define Span Hierarchy Structure spans from e2e flow down to individual calls. Step 2: Instrument Code Wrap operations in tracker.span() calls. Step 3: Set Alert Thresholds Configure alerts for latency exceeding expected ranges. --- Span Hierarchy e2e flow (root) ├── rust hotpath call (5-15ms) │ └── rpc eth call (5-20ms)…
