Performance comparation between Docker v1.13 and v1.10.3

[supereagle]

Conclusions

• The performance of Docker v1.13 is much better than v1.10.3.
• The CPU spike is because docker processes request much faster than before, the benchmark sends more request in the same period. Explanation from the author
