W3TC

One Click can change the whole site

I was a happy go person when my site was loading at 3 sec just with the W3TC plugin installed.
I decided to go for the pro package and immediately when i activated the plugin my site went from 3 sec loading time to 30 seconds loading time .

my question is

i have
w3tc
humminbird
cdn

how do i know which option to enable as i know now all three are on conflict mode.
