So I have a new Mac Mini 2018 i7 8gb RAM, and I've noticed some very noticeable RAM shortages with seemingly simple web browsing, particularly using Safari. Any time I load a heavy site like slickdeals.net, Safari gets destroyed, I notice a ton of hiccups and slowness, whereas with Chrome it's smooth. Upon inspecting Activity monitor I notice each tab in Safari is a ridiculous 1GB each (for a total of ~3GB), whereas on Chrome the same 3 tabs are about 1GB combined. I also notice a ton of swapping happening, obviously the 8gb is insufficient with Safari's lavish RAM consumption.

But the bigger question is, why is Safari eating so much RAM compared to Chrome? Does anyone know what's going on, is there some kind of bug or issue or is Safari really this poor with regards to memory management?

EDIT: I've done some more testing and so far it seems it's just that one site bringing down Safari, other sites seem normal, perhaps it's an issue isolated to one site. I still find it odd that Safari is going overboard though. I just tested 5 tabs with slickdeals.net, and each tab is 1GB for a total of 5GB.

EDIT 2: I just disabled Adblock in Safari and that seems to be the culprit of the anomaly.
