Sleep Image 50% smaller in late 2013 rMBP

[duffer6]

I recently purchased the late 2013 15, rmbp w/2.3 16GB and 512. I noticed that my sleep image is only taking up 8GB of SDD space. In the past it was my understanding that the sleep image matched your onboard RAM gb for gb thus with 16GB of onboard ram I would have thought my sleep image would be clocking in at 16GB. Did Apple change something with Mavericks. BTW the wakeup response time on this machine is wicked fast.

Curious your thoughts?

That's a first I've heard of it, maybe it has to do with Mavericks' memory compression?

Could be, odd but a welcome change. I hated giving up 16GB on 256 ssd, not as big a deal on my 512 sad.

Are you sure it is 8GB? I have read other people saying that they have 16GB RAM and the sleep image file is only 1GB.

But yes, Mavericks changed how this works. It's a good thing. If someone has a 16GB/256GB configuration, you don't want 16 gigs of that to be taken up by the sleep image.

See attached. Yes it is 8+GB with a 1GB swap file.

Interesting. Either way I was glad to see this changed when I discovered this. I had been thinking of going with a 16/256 config, and I was worried about how much space it would come with out of the box.

I'm just really glad Mavericks changed this. Even if you have a 512 or bigger SSD, you don't need that many gigs being take up by a sleep image.

People here are saying 1GB: https://twitter.com/schwa/status/392880747922477056
