My website uses Sage 10 with the Bedrock boilerplate, and for some reason I just
can’t exclude some Javascript files from delayed loading. It’s a pity, because Engrish
text in the plugin aside, it’s great.

I used to pay and use Perfmatters to combine CSS, as I didn’t like the WP-Rocket
implementation. But stopped using the former after finding Debloat to save some 
money. I’m not sure if it works as well as Perfmatters, but does do what I need 
it to do. It fixes all the PageSpeed insight recommendations about CSS, and my site
loads very fast with it enabled for combining CSS, with WP Rocket handling everything
else. I have a complex membership site with 60+ plugins and was able to get page
load down to 0.9 – 1 second, even for logged-in users – and AffiliateWP still tracks
cookies properly, and all else works. On the blog I also have, I got page load down
to 200 – 300ms. Like other combine CSS plugins, I had to obviously add some exceptions
to get some things to display properly, but that is pretty standard stuff. Anyways,
this plugin is very good. I highly recommend it if you need to combine CSS.

A bit tricky to tune it up and get it running perfectly, but one you do, it can 
speed up your site more than any other minifying/optimizing plugin than I’ve ever
seen before. The tricky balance is figuring out which JS and CSS you can get rid
of or delay without negatively impacting the operation of the site. In some cases
you need to get really familiar with your web browser’s developer tools so that 
you can see which scripts need to run. I also appreciate that this plugin doesn’t
try to do too much. Some of the optimization plugins go way overboard with features
and then seem to do none of them particularly well while simultaneously spamming
your Wordpress dashboard with « Upgrade to Pro » messages. This one doesn’t do that
at all.
