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
