If you want to make the units common across all three tests, netperf 
accepts a global -f option to alter the output units.  If you add -f M 
netperf will then emit results in MB/s (M == 1048576).  I'm assuming of 
course that the MB/s of Apache and nginx are also M == 1048576.

happy benchmarking,
