This MacBook Air also has 8GB RAM. I've had approximately five tabs open in Safari. Safari is primarily the most active app, with a few others minimized (Photos, Skype, Notes, Messages). Apps and system are responsive overall for a four plus year old system (Mid 2013 MacBookAir6,1).
The "This page was reloaded because it was using significant memory" message is displayed in the Safari tab that is reported to have the significant memory usage problem.
Update: The screenshot shows the message that Safari adds to the browser tab. As I noted above, the message appears on other sites, not just iMore, although that's where I first encountered the message.
