Subject: [bpf?] [net?] socket test data of ebpf sockmap/redirection and TCP/IP stack

Thank you for your attention!

The testing tool is Fortio.First,start a Fortio server container,and then
start a Fortio client container to send messages to the server container.
Compare the performance indicators of using ebpf sockmap/redirect and TCP/IP
stack.

test cmd:
fortio server:docker run -it -d --name=fortio-server fortio/fortio server
fortio client:docker run -it --rm --name=fortio-client fortio/fortio load 
              -c $connum -t 30s -qps 0 -jitter=true -payload-size $payload 
			  -quiet http://172.17.0.2:8080

As I increase `connum` or `payload`,the performance improvement gradually
becomes less significant or even decreases.

Host Configuration:16 CPUs(x86_64),64G mem
OS kernel version:5.10

here are the test datas:
