When trying to render a relatively simple page consisting few thousands of text lines in a table, any current browser will cause mouse cursor to lag for some time, then you’ll discover it consumes at least 2 GB ~ 4 GB of RAM. YouTube lags like I have 2 cores instead of 16. Any electron app is either clunky or too clunky, also either hungry or too hungry.
I’m sorry but I don’t have time to look up other cases.
Any intuition on why we’d expect opening the same page on a newly implemented browser engine that implements all equivalent standards and functions will consume less resources?
That’s not an expectation. The experience is that this became a reality thanks to google, and that it will only get worse in the future. More competition within browsers is the expectation. Better chance for better frameworks to emerge. Eventually it may cause google code to shift into a better overall state too.
