@fribbledom I don't know...mine has 32GB and it's more than enough for incredible amounts of operations. Also I have about 200+ tabs open in Safari under something like 20 groups and there's literally no slowdown. If I have to relaunch it, it takes about 1 or 2 seconds. It hasn't been an issue for years and years for me.
Also I get the same kind of response on my iPhone and iPad Pro.
