⚡ Bolt: Refactor TelemetrySystem to use O(1) ring buffer#493
Conversation
Replaced `Array.prototype.push()` and `Array.prototype.shift()` with a circular array and `dataHead`/`dataCount` pointers to eliminate O(N) shift operations and reduce garbage collection pressure. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>

💡 What: Refactored
TelemetrySystemto use a circular array (ring buffer) instead of standard arraypush()andshift()operations.🎯 Why: In high-frequency recording loops (like the telemetry data), using
Array.prototype.shift()when the buffer exceeds itsmaxDataPointscauses an O(N) array re-indexing operation, leading to performance degradation and high garbage collection pressure.📊 Impact: Expected to reduce execution time for telemetry shifting/updating significantly by converting O(N) shift operations to O(1) modulo index assignments. In benchmark tests (
benchmark_telemetry.tsandbenchmark_telemetry_stress.ts), it shows an improvement in time per operation for worst-case buffer shifting.🔬 Measurement: Verify by running
tests/benchmark_telemetry_stress.ts. Time per iteration should remain stable in O(1) instead of degrading linearly. All telemetry UI and tests should continue to pass normally.PR created automatically by Jules for task 3503670957296995953 started by @dhaatrik
