Hello @nichere
Thank you for reaching out.
The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, and the technologies available on the server. Since everyone’s site, traffic and theme are different, there is no one-size-fits-all solution.
In your case, as per the Google Page Speed report, there is much room for improvement.
The bottleneck of your website performance is images and render-blocking resources.
You should convert the images to webp (W3TC Webp converter), Lazyload images (W3TC Lazyload option) and properly size your images (This should be done first with some image optimization plugin or manually)
W3 Total Cache can eliminate render-blocking resources. To do this you should also Minify the assets (JS and CSS)
Once minified you can eliminate render-blocking JS by changing the embed type in the Performance>Minify> Minify engine settings:
Eliminating render-blocking CSS is a Pro feature
You can also delay external scripts to remove them as render blocking with the Delay scripts option in the W3 Total Cache Perfomrance>General Settings>User Experience
However, this is also a Pro feature.
Thanks!
