CloudWorth vs YABS / sysbench: what benchmarks still miss

YABS and sysbench are the lingua franca of VPS benchmarking. Great for scoreboards — weak alone if you need proof of overselling, disk fraud, or a support-ready case.

What YABS / sysbench are great at

YABS wraps familiar fio/iperf/Geekbench-style outputs; sysbench is flexible for CPU/memory stress. They answer: “How fast can this box peak?”

Useful for shopping comparisons. Less useful for explaining whether slowness is noisy neighbors, overcommit, or simply weak hardware.

What overselling proof still needs

To answer “am I oversold / mis-sold?” you typically need:

  • Peak-hour steal time series, not only a single score
  • Burst vs sustained disk cliffs (classic cache-as-NVMe tricks)
  • Hardware generation vs asking price
  • Structured reports / ticket text for support

Where CloudWorth fits

CloudWorth is not “another YABS.” It focuses on evidence and FinOps: steal sampling, disk-cache exposé, hardware aging, price collision, complaint PDFs, and downsizing hints.

Zero-dependency probe, ~10s results — ideal when you already suspect overselling. If you only want a public scorecard, keep using YABS.

Best combined workflow

Use CloudWorth to confirm overselling/fraud signals, then YABS to quantify the gap versus a healthy peer of similar specs. Evidence + scoreboard beats either alone.
