Great piece, Joe. I have an old Dell machine that I use as a Squeezebox media servier amongst other things. Its always worked well but it is very leaky in terms of memory usage. I heard your comment about the command to "reclaim" memory being potentitally useful for media servers so I set this up as a Cron job and its really done the business. Thanks again.

Though I never suspend/hibernate, I have 16GB RAM and don't have a swap partition and Linux has been working all fine since years.

SSDs have quite the endurance, I would not worry about it. 700-2000TB written per 250gb SSD is about the endurance you can expect from an SSD.

You should mention what the alternative to swapping is, it doesn't just "not swap" with a lower swappiness, it will choose to drop pages from the page file instead of swapping, which could potentially be worse performance if your workload is constantly needing to read and write from files on the filesystem and less so accessing anonymous pages .

Yep. I don't even mess with this anymore and leave it set to the defaults. It's a trade off either way. :)

nice video... cache that was mentioned to drop... that is the page cache stored in RAM.. and has nothing to do with cpu cache... just to make it clear for others who are watching this..

How come SimpleScreenRecorder is running at 67% CPU but is noted as "S" (sleeping) ?
@hannesthiersen81705 жыл бұрын
Hey Joe. You're contradicting yourself when talking about swappiness. You're saying that if the value is 60 the system starts swapping when 60% of the memory is used, but then setting the swappiness value to 15 would mean the system starts to swap when 15% is used according to this logic. After you've set the value to 15 you state that it will start swapping when 85% of memory is used which contradicts the previous statement.

Sorry if I didn't make it clear enough. Swappiness is less likely the lower the number is. :)

What happens if I set my swappiness to 1? Does that block most non-essential swap operations while still letting system crashes write to it?
@EzeeLinux5 жыл бұрын
Something like that. It's not exact. If you want to limit it 10 is about the lowest you should go. :)
