I tried using phantomjs in the past to serverside render a complex backbone application for SEO, and it was taking over 15 seconds to return a response (which is bad for SEO).

Looking at the prerender's source I did't see any caching mechanism.

What kind of load times have you see rendering your apps?

Have there been recent significant improvements in phantomjs's performance?



I run http://www.brombone.com. We provide prerendered snapshots as a service.

You can get it faster than 15 seconds, but you can't really get it fast enough. We precache everything. I would strongly recommend against trying to process the pages in realtime.
