    2018 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Moby VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).
docker run -it --rm --privileged --pid=host justincormack/nsenter1

                Google DNS rate limiting of ICMP - (blatantly stolen from @dupuy's post https://goo.gl/pPjWH7)
              
          
    TL;DR: At the risk of repeating myself: Google Public DNS is a Domain Name System service, not an ICMP network testing service.
If you want to measure the quality of your DNS service from Google Public DNS, you should use a dnsping tool (https://github.com/farrokhi/dnsdiag [Python] or https://sourceforge.net/projects/dnsping/ [C#]) to send real DNS queries and check for responses. Note that while traceroute -U sends UDP/53 packets, they are not DNS queries, and traceroute -U is not a substitute for dnsping.
If dnsping shows significant levels of unanswered queries (and especially if ping and traceroute do not show any drops), you should check whether your IP address is generating more than 100 queries per second (the default per-IP address QPS limit for Google Public DNS). If you are legitimately generating more than 100 QPS and need to increase your QPS limit, you can [request an increase through the Google Public DNS is

                How effectively delete a git submodule.
              
          
    To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
