Browsers eating RAMI reached a point where I could barely hear the podcast I was trying to listen to. That's how loud the fan was. Then I closed down all open Chrome windows, and a few minutes after, the fan went silent. So I decided to see if it was just me.How I measuredI ran the 2-tab test in a completely fresh macOS install on a virtual machine. Then I ran the 54-tabs test on my own Big Sur installation, but with all extensions disabled. To record a usage snapshot ~250 times per second, I used psrecord.meer ...So no, it's most likely not as bad as it looks, but that doesn't change the fact since switching to Safari, I almost forgot what my fan sounds like.
