## Bifrost Process Stats (single instance)
|
|
|
|
| Phase | CPU Avg | CPU Peak | RSS Avg | RSS Peak |
|
|
|-------|---------|----------|---------|----------|
|
|
| Overhead | 20.7% | 66.9% | 332.8MB | 640.2MB |
|
|
| Stress | 29.9% | 73.5% | 639.5MB | 789.2MB |
|
|
|
|
## Method
|
|
|
|
- **Single instance**: All tests run against one bifrost-http process at 1000 RPS
|
|
- **Overhead measurement**: Mocker at 1000ms latency, calibration (Vegeta->Mocker) subtracted from test (Vegeta->Bifrost->Mocker)
|
|
- **Stress test**: Mocker at 1000ms latency, verifies 100% success under sustained concurrency
|
|
|
|
## Notes
|
|
|
|
- Overhead values are in microseconds (µs), stress test values in milliseconds (ms)
|
|
- Overhead ignores the mocker jitter, local network request queuing. In real-world the P99 overhead will be approximately 100 microseconds.
|
|
- Tiered overhead thresholds: mean<5000µs, p50<5000µs, p90<10000µs, p95<20000µs, p99<100000µs
|
|
- P50/P90/P95/P99 represent percentile latencies
