I have just added a new feature for long threads - this work on modern versions of Chrome, Edge and Opera (and yes, Internet Explorer 11).

When browsing a multi-page discussion the next page in order will be loaded in the background (after everything on the page has finished loading). This means by the time you hit "Next" or the page number) the page should show instantly instead of waiting for the server to respond.

Firefox and Safari do not support this feature.

Out of interest, is this a standard feature with a name that I can search for, or is it something custom?

Nope, preload is used for resources - and I have implemented this years ago (including preloading of ad scripts, css and more). I also implemented preconnect years ago (which is good on slower mobile networks).

This is the link rel="prerender".

Also preload is only expensive if resources are loaded and not used within ten seconds. My code loads only resources used on that page so it never goes wasted.

Thanks; might have to investigate using that one. Assuming that you actually meant prerender :)

There's a great chance that users will load the next page. Modern versions use "prerender" but don't actually load and execute external scripts until later when you open the page. It basically loads the HTML and render the local content. Our HTML is very light and it's a balance between speed and functionality.

Exactly. If you open Chrome tracing and save the log as a son you can see the NoState actions.

Just wanted to quote:

it will work if the following two conditions are met: a) the user is not on a low-end device, and b) the user is not on a cellular network.

Ultimately if your device and connection can give you faster load times, that's what you get.

It'd be great if we could opt-in to auto-loading the next page of posts and inlining it, like more modern forum software does. The click target for the page numbers is awfully small...

(Also markdown please! BBCode is horrific.)

"Next" is a bit larger.

I have tweaked this a little - not "anticipating" the load of the last page as I've noticed that it sometimes wouldn't bring the most up-to-date content in a fast-moving thread (like the Trump thread currently). It could happen that the browser would load the second last page and after finish processing, it would load the last page behind the scenes, which by the time the visitor finished reading the on-screen content would already be out-of-date.

This means the next page on longer threads won't be downloaded in advance when it happens to be the last one - this includes the second page in two-page threads.

After a few weeks of testing I have decided to remove this feature as it conflicted with another feature I am working on.
