This sounded like a potentially useful feature for web developers, to improve perceived loading speed without having to use JS (which may be desirable in some situations). But reading Google's notes on the subject is like a splash of cold water: http://code.google.com/chrome/whitepapers/prerender.html http://code.google.com/chrome/whitepapers/prerender.html
TL;DR: Only one page may be prerendered at a time per-instance of Chrome (not per-tab).
It would be nice to know if this just limits simultaneous prerendering, or if only one link may be prerendered and it must be clicked on or "evicted" before any more prerendering will occur.
- eridius 15y agoI can't speak definitively, but I doubt the prerendered page needs to be visited before another one can be prerendered. If that were the case, I could open a google search and leave it in a background tab and never ever get prerendering ever again.
- spiralganglion 15y agoYes, that's what I'm afraid of. It's not clearly stated if that is or isn't the case. Their wording is ambiguous. I'd test this myself using the dev build of Chrome, but I can't install it where I am. Anyone else?
