The inline cache methodology emphasises fast first page loads. It acts on the basis that opening HTTP connections is slow, and that it is therefore faster for the resources to be inlined, but that we also want to cache those resources so they don’t have to be re-downloaded.
That’s what WP Inline Cacher does. It automatically renders your stylesheets inline on first page load, and caches them in the background. On subsequent page loads, the resources are no longer inlined – so your page weight is smaller – but are automatically retrieved from cache.
See https://github.com/ChrisBAshton/inline-cache for more details.

“Read More Right Here” uses the jQuery framework already included with WordPress installations. RMRH hooks into the WordPress creation of the 
“more” link and adds a custom class. When your blog is loaded, all links of this custom class are modified to no longer send the user to that post’s 
single page display when clicked. Instead, the WordPress database is queried for that specific post, and all content after the  tag (i.e. only what you need) is returned. 
The new content is then immediately displayed to the user, inline with the opening content.
