nginx - How to generate 1Gbps in Apache Bench?

Question

1. I have a i7 processor (8 core) with 16GB RAM
2. I have installed Windows Docker
3. I have created a Ubuntu docker instance
4. In the Ubuntu instance I have installed Nginx (8 workers)
5. In the Ubuntu instance I have installed Apache Bench (ab)
6. In the Ubuntu instance I have set high ulimit values as shown below

# ulimit values

root@c8c1c6a106c2:/# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited

file locks                      (-x) unlimited

Now when I run the following ab command In the Ubuntu instance I get only 137.73 KBytes/sec (1.1MBits/sec). While my network card can support 10Gbps, why the through put is very less and how can I improve it ?
