ODOO worker Calculator. Estimate number of memory and workers can be used. In case NGINX and Postgresql performance count then at final use some less workers to take breathing for other resources

How to use !

cd /opt

sudo wget https://gist.githubusercontent.com/tejastank/b475328e6eec77f6f084bcb6e4301e64/raw/db98265456328620a69533f8c09aafdb40626602/odoo-worker.sh

sudo chmod +x odoo-worker.sh

sudo ./odoo-worker.sh

sudo apt-get install bc

in case you don't have bc command install

How to check bc install or not !

on command link, type

man bc

if you see documentation, mean installed, else do install.
