Results are not varying much since last 6 kernel releases. There is a very marginal increase in CPU efficiency.
Latencies have also risen but not by more than 5%.
No size specified, using 252 MB
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
