Last week, a great deal of discussion about ad blocking and its effect on memory usage took place. This makes a lot of sense, and explains why my memory usage has always been really high.
I’m not sure there’s a lot you can do about it. One of these days I’m going to get around to standing up a pfsense box, which, among other things, can serve as a web cache and block ads for an entire network. My family has enough machines to justify that, and, given that security is what I do for a living, it’s something I need to be experimenting with anyway.
