- Unit information
- ================
- File size = megabytes
- Blk Size = bytes
- Rate = megabytes per second
- CPU% = percentage of CPU used during the test
- Latency = milliseconds
- Lat% = percent of requests that took longer than X seconds
- CPU Eff = Rate divided by CPU% - throughput per cpu load
- Sequential Reads
- File Blk Num Avg Maximum Lat% Lat% CPU
- Identifier Size Size Thr Rate (CPU%) Latency Latency >2s >10s Eff
