Page optimization : How to know if LScache does something ?

Hello
I have changed host recently and this host has LiteSpeed server…
So I installed LSCache and uninstalled WP Rocket…

I have activated several page optimization features (CSS and JS minification, JS and CSS combination…) but when I look at the source code of my page it looks just the same as when it’s not activated…

So is there a way to know that it’s working ?

THanks
