swap

[ub9876]

if your laptop had an SSD only and was running Xubuntu 13 ......would you still do the swap adjustment where you change it from 60 to 10???
or is this just for regular HD laptops...??

How much RAM?

how do I see how much ram???

Hi ub9876.

To see how much RAM your system has available (and how much is being used):

free -m

Regards.

what does this say????

total used free shared buffers cached
Mem: 993 669 324 0 27 424
-/+ buffers/cache: 216 776
Swap: 1012 0 1012

Your computer only has 1GB of RAM (993 MB total ~ 1GB).

I would leave swappiness as it is because it does not matter whether you have an SSD or a conventional HDD; it is purely dependent on the amount of available RAM in your system.

Since you only have 1GB, your computer will most likely require heavy use of swap space regardless of the settings.

It means you have 993MiB of RAM, 669MiB of which is in use, but most of that is cache, which can be dropped from RAM whenever it's needed for something else. You have 1GiB of swap, but don't use it right now. In fact, with Xubuntu you won't use swap very often with 1GiB of RAM. I only use more than 1GiB when rendering pdfs at high resolution. Right now, my Xubuntu uses 290 MiB of 3000MiB available, excluding cache.

OP hasn't described the intended usage.

OP hasn't described the intended usage.

OP is asking if he should change swappiness from 60 to 10 because he has an SSD.
10 swappiness, which I am using currently, means that ubuntu will try to wait as long as possible until it swaps which is good for computers >4GB RAM.

However, he only has 1GB, and whether he changes swappiness or not will not drastically affect the frequency of swapping and therefore will not have a profound impact on the life of his SSD.

If anything, setting such a low swappiness on a low memory system would result in more lag because at around only 300MB free, ubuntu would wait as long as possible before swapping and this might cause some larger programs to be less responsive as the system only swaps when the RAM is on the verge of being completely filled instead of leaving some leeway.
