    Is it normal to have pinned tabs eating up so much RAM. The other day I had a bunch of apps open across 4 desktops and I noticed my computer was running slowly, so I went and checked Activity Monitor, and my pinned tabs each were using 250 MB! Is this normal to have tabs eating this much RAM?

    I have a screenshot from just a minute ago, showing what I mean. These are not as bad as they were, but they are still almost at the top of the list.

    Not just pinned tabs, but any open tab will consume about that much memory, at minimum. With sandboxing in browsers, you get a separate process to run the specific tab/window in. So, you get basically a clone of the main browser process and all the extra stuff that comes (Flash, graphics, text, Java, etc) with a given webpage. And the more you're on the interwebs, the more RAM gets consumed, for the tab/window/process.

    Have not looked closely in a while, but, Safari does use a fair bit of RAM during the course of a day.

    Should see in Activity Monitor a "Safari" process and per the provided screen grab, a process for each tab/window open.

    I've never understood why webpages consume so much memory. I have some NY Times articles open right now and they're using over 300MB of RAM. Why? They probably only take a MB or so to download.

    Everything seems to be very RAM hungry nowadays. Which is why, personally, I consider 8GB of RAM the very minimum needed on my systems.

    Just to show how much an open tab/window in a browser is, my homepage is a blank page. And even that chews up 130
