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.

//To fetch a branch, you simply need to:

git fetch origin

//This will fetch all of the remote branches for you. With the remote branches 
//in hand, you now need to check out the branch you are interested in, giving 
//you a local working copy:

git checkout -b test origin/test
