Mozilla ran a Snooze Tabs experiment in 2017 but did not integrate the functionality natively in Firefox.Most Chromium-based web browsers support the experimental feature Tab Groups, and with that feature comes another experiment that supports Tab Groups Collapse Freezing which improves resource usage.The downside is that you of course need to re-load old webpages, which is no biggie for me when the alternative is a slower system. And you just consolidated a lot of deferred writes in one disk wake up. Freeing up RAM is great for starting a new app that needs lots of memory and the app or data it needs has not been accessed recently. The Mac will slow when after it uses up RAM and has to to pageouts/pageins.ĭoing a purge forces macOS to clean its RAM cache, doing I/O writes if necessary, then put the pages on the free list. MacOS operations in theory meets macOS in reality, and reality wins. Even when you have inactive memory macOS will need to do I/O first to save the data to disk before it can reuse the RAM. Writing to disk during pagein/pageout activity slows down the Mac when RAM gets full. Saving to disk slows down the system, virtual memory slows down the system, period. Apps that leak memory can’t have it reclaimed, as the “leaked” memory belongs to the process that’s leaking it. Firefox is a quite good browser too but has far fewer useful extensions.Īnd the built-in ad-blocking in both Mac and iOS versions of Brave (using, from what I understand, the guts of uBlock Origin) is very convenient, especially on iPhone.īig Sur is supposed to make it easy to translate Chrome extensions for use in Safari, so it will be very interesting to see how things shake out next year.īut the OS will do that on an as-needed basis by itself. But Chromium apps can use any of Chrome’s extensions, and I use a ton of those, ranging from privacy enhancers to ad-blockers, to extensions that customize Reddit and YouTube, to ones that save webpages as epubs, or implement dark mode on pages with a click, or enable right-click on sites that try turning it off, or grabbing RSS feeds, or block tracking pixels in email. I find that Chromium apps - Brave, Epic, Vivaldi, etc - are simply faster than Safari and handle most web pages better for some reason Safari tends to bog down when visiting some websites. I actually live inside four different writing apps. If I hadn’t auto-suspended those Brave tabs (I’ve got a backlog of 6 unwatched YouTube videos alone that would have eaten up RAM in preload) I’d have been left with less than 4Gb RAM and a lot of data would have been written to disk, which, in combination with reading from disk to retrieve it would have made the Mac decidedly sluggish.Īdd in the fact that Chrome and Chromium apps have a tendency to experience memory leaks when used over long periods (and I only restart my Mac every 3 weeks or so) and purging RAM becomes a real necessity if I’m not going to quit and restart apps. 40Gb RAM installed and this is my current RAM situation: I currently have six apps open, and two dozen menubar utilities, and 49 tabs open in Brave (most RAM-suspended) and 15 tabs open in Safari. I was experiencing that too with 16Gb RAM, but in situations that aren’t uncommon for me I experience them with my current 40Gb RAM as well. My Mac is good at not crashing when RAM fills, but I regularly use it with immediate, very noticeable, positive effect on my 16GB machine.
