Have an 8GB Mac, Retina Pro 2013/14 model, now with 256 GB SSD disk space
I run between 45-250 tabs across browsers (Chrome/Brave), starting to use Firefox as well
But don't think this is going to improve
The disk in its worst time writes like 3TBs in a week easily.
Majority attributed to kernel_task
PC runs usually at 6 GB memory used out of 8 and Cached and Swap show like 4-5 GBs additional.
Memory pressure remains green but in between surged to yellow and red slowing down the PC when more applications open.
Using Chrome extensions as well 5-6 of them,
It appears Mac has some mismanagement here allow SWAP to eat up the hardware! But they are not taking responsibility and pinning it on Chrome for low-quality leaky code!
Well to come back to you, the last time I checked, ( a few post above you ) I did a Tab Overview and had an additional 500GB write. That was awful. But it was worth testing it out. At the time it was posted. Jul 8, my total write was at 950GB Write.
Today, it is at 2.5TB. No Tab Overflow ever used. Just normal surfing.
I have no idea what caused it.
