# SLIM Adaptive Capacity Sweep Report

**Generated:** 2026-06-26 08:53:08

This CI report combines the sink-backed capacity sweeps and the write capacity sweep into one markdown artifact.

## Sink-Backed Modes

#### Fire-And-Forget Clients=1 Payload=16384B

Best offered aggregate rate: `128000` msg/sec
Estimated capacity offered-rate interval: `[128000, 130125]` msg/sec
Best observed node throughput: `7210.38` msg/sec with 95% CI [7174.95, 7245.80]
Best sender-completed throughput: `7130.47` msg/sec with 95% CI [7093.50, 7167.44]
Best node CPU: `41.15` % with 95% CI [40.91, 41.39]
Best total CPU: `246.58` % with 95% CI [245.57, 247.60]
Stop reason: refinement narrowed the estimated capacity to offered rates 128000 through 130125
