Comments:
* DONT_BUNDLE is ignored when sending a message *except for SSWT*
** That's why SSWT -B is slow: messages are not bundled
* SSWT had quite a high variation between runs
* SS is slow with only 1 sender thread
** With 2 threads SS (-B/+B) achived ~ 118
* TQ achieved the highest perf regardless of the number of senders. Note that 120'000 msgs/sec ~= 120MB/sec, that's close to the max throughput of 1Gbps ethernet of 125MB/sec
