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
