Measuring Peak Injection Memory Bandwidths for the system
Bandwidths are in MB/sec (1 MB/sec = 1,000,000 Bytes/sec)
Using all the threads from each core if Hyper-threading is enabled
Using traffic with the following read-write ratios
ALL Reads : 126912.2
3:1 Reads-Writes : 66042.0
2:1 Reads-Writes : 102700.1
1:1 Reads-Writes : 88529.7
Stream-triad like: 93077.4
All NT writes : 78795.6
