Open Litespeed: Tuning Server Settings Part 2
In OpenLiteSpeed Tuning Server Settings Part 1, I outlined some of the most common settings I usually tweak. Well in Part 2 decided to just automate the tuning with a shell script I wrote.
The shell script would usually be run in SSH telnet after initial OpenLiteSpeed installation. Feel free to modify it for your own needs.
Save contents in file named lsws_tweaks.sh and chmod +x it. By default, OpenLiteSpeed sets number of workers to just 1. This tuning script sets number of workers to 1/2 the number of cpu threads detected on your server. So if you have 8 cpu threads, this script will set number of workers to 8/2 = 4 workers.

Sample output from the script when ran includes a side by side comparison output for the tweaked vs default settings so you can see what was changed.
