That's certain one of the statements of all time. All major OSes compress memory at this point. I'd be curious to see how OoM acts on macOS -- I've seen it on Windows [NT4] and Linux over the years. I've not seen an OS handle it as well as NT does/did.

It’s like an analogy from high school. 1 is to 8GB as 2 is to 16GB. See, they’re analogous.

This is not news, has been the case since Intel macs, though the rise of Electron apps has reduced the MacOS advantage. I do have an 8GB M1 mini I use for development and the only way to make it run out of memory is to run Docker, otherwise it's perfectly fine.

You don't know what you're saying. That's because of virtual memory and its much slower. Apple's claim is bullshit and they lie.

Every modern OS compresses memory, not just the MacOS. And no 8GB is not equivalent to 16GB on a Mac. Apple says it so foolish people believe it, but its not true. Sure unified has advantages, but they're saying BS.

I just upgraded my windows workstation to 128gigs so i could load larger language models for only $300. 8 gigs seems rather absurd of apple. Apple charges 200 bux for 16 gigs or 400 bux for 24 gigs.

I just put 64 gigs of (fast) memory and a (very fast) 4 TB SSD in my laptop for a total of $600.

In the MacBook Pro configurator the equivalent upgrades look like

36GB->64GB RAM: $400

1TB->4TB SSD: $1000

Do they? What did nt4 do that was so great?

Linux zram seems effective for marking some memory as compressed swap. Alas it doesn't play well with zswap, reportedly, which lets real swap drives also be compressed. But should be useful in many scenarios to quickly switch between compressed memories in a wide number of cases.

It's perfectly fine for the Mac's primary use case these days: a thin client into a real computer for performing actual work.

We should congratulate Apple for building the world's sexiest VT100 and Wyse WinTerm in one box.

Earlier quoted context omitted.

Does Debian do this by default? If so, can I disable it for a performance increase?

Compressed memory is a performance increase. CPUs are fast .

Depends on what sort of performance you're optimizing for, does it not?

Horse shit.

What Apple wants to happen is for you to eat into your soldered SSD's endurance (TBW) through virtual memory swapping out RAM to your storage volume so that you Buy More Stuff.

I investigated my unexpectedly high disk writes and made a few changes, disabled some MacOS services, disabled write-caching for video in Firefox etc and this reduced my write volume by tens of gigabytes per day. By this point I think I'd written 50TB of the drives TBW in a year which was significant/

This is particularly relevant if you use a mac with a soldered SSD, because when you approach endurance ratings the drive will probably fail spectacularly and your computer will unrepairable by reasonable means.

Most people buying the entry level macbook pro are probably not loading 128GB language models.
