The OS still expects swap to be there. Windows 7 and 8 pre-fetch regularly used programs. Which is why it appears snappier.

Turning it off doesn't make the system any faster when there is plenty of memory and makes the system more likely to fail when running out of memory.

Turning it off has absolutely no benefit.

lucas_maximus,

"The OS still expects swap to be there. Windows 7 and 8 pre-fetch regularly used programs. Which is why it appears snappier."

I'm not sure how MS's implementation works, but swap isn't fundamentally needed for this feature. Pre-loading to ram could work without swap too.


"Turning it off doesn't make the system any faster when there is plenty of memory and makes the system more likely to fail when running out of memory."

Sure, if swap gets zero use, then the performance should be identical. The "benefit" of having swap is having it "just in case" as both you and I agree. But you have to recognize the implicit truth in that if 4GB total ram+swap is enough for your work "just in case", then 8GB total ram without swap would clearly be as well.

The whole reason for swap is to make software work in ram constrained systems. I haven't seen the "your system is critically low on resources" warning on systems with even less total ram than my new ones. You can make fun of Kochise for not running swap, but frankly he doesn't need it.


"Turning it off has absolutely no benefit."

It increases disk space. Haha, just kidding, just be more careful with "absolutely" ;)

I also disabled swap on my 1 GB Windows XP without any problem so far, for 5 years now, running up to 3 or 4 applications at the same time. I used to work on Atari machine with 1, 4 or 14 MB and things were working pretty fine. We have now 1000x more power and complain ?
