Często zadawane pytania
- When should I use queue depth?
- When estimating IOPS from depth and average latency (fio, storage tuning).
- What does a deeper queue give?
- Often higher IOPS, but higher p99 latency — a trade-off.
- What values are typical?
- iodepth 1–32 (lower for HDD, higher for NVMe); latency depends on the device.
- What looks “bad”?
- High depth with rising p99 and no IOPS gain — queue saturation.
