I have run a simple test. The following tabs have been opened first in Safari. My M1 Mac was then turned off and powered back on, I then opened the same tabs in Edge. 4 x Gmail tabs (each with a different account) 1 x Youtube Music tab playing in the background 1 x Bloomberg News tab Safari RAM usage between 6 and 7GB Microsoft Edge Same tabs Edge RAM usage remained stable at under 2GB I'm at a point where one gmail tab + youtube will use all my RAM and be forced into swap. It slows down my mac to a point where I simply cannot use it. There is a clear massive requirement of RAM by Gmail in browser but nowhere near as high in Edge. I never thought I'm gonna say this but I have started using Edge as my default browser, all these years Microsoft has tried to convince me to use it, finally they made it happen. I intend to create a more comprehensive post with screenshots and everything. P.S. the only reason I have even tried Edge was curiosity relating to their Bing integration with ChatGPT. Don't worry, Bing is still horrible but their version of ChatGPT is nice.
