Linux sysctl configuration and tuning script | Shell Tips !
Frequently when I setup a new server (or a bunch of them) I use a small shell script that will go thru all the basic linux sysctl config. I decied to share it. I always change it a bit according to my needs and the application/services that will run on the server. Though having a script to automate some of this manual tuning is quite useful. Use it at your OWN risk. There is no silver bullet, make sure to understand each parameters and that they fit your needs/usage/network/OS.
