What's your swappiness set to, eh?

[chrispop99]

sysctl.conf is a file in /etc folder.
it is better tat u put this 'echo 10 > /proc/sys/vm/swappiness' in /etc/rc.local file b4 the word 'exit'.

Not in mine. I looked there and it's no where in that folder. The closest thing I found to it is sysctl.d

It's a file, not a folder.

In /etc, scroll right down past the folders to the files. (It's been there in every version of MX, and other distros I've run.)

Changing swappiness doesn't make a huge difference to performance, but is worth doing if you are using as SSD, just to keep writes to a minimum.

Here's a handy command that will help:

Code: Select all

$ locate sysctl.conf
/etc/sysctl.conf
/etc/sysctl.d/99-sysctl.conf
/etc/ufw/sysctl.conf
/usr/share/doc/procps/examples/sysctl.conf
/usr/share/man/man5/sysctl.conf.5.gz

Thanks found the folder but there are no settings for it. This is what it says in there. #

# See /etc/sysctl.d/ for additional system variables.
# See sysctl.conf (5) for information.

Thanks. But it looks like it's more trouble than it's worth as there are no settings when I get to it.

You're supposed to edit the said file in root to add the line of text as set out in the link in the first post.

Thanks, I opened it in root but there was nothing to edit that said anything about swap. I am going to leave it alone. Too much trouble. Thanks anyway.

If you had read the linked article about setting swappiness in 'Mint', you would have seen that you create the swappiness entry by copying/pasting the information.

I read it and there is nothing on my computer that indicates what it's set to. If default is 60 then I guess it's 60, but I don't know.

An interesting read about how to adjust your distros' swappiness. Anybody ever tinker with this? My m12 is set to 60. As far as swap size goes, the author suggests:

This is a dedicated space in your hard drive that is usually set to at least twice the capacity of your RAM

Happy Friday!

60 is the default.

If you want to check, do this in a terminal:

Code: Select all

cat /proc/sys/vm/swappiness

It will return 60.

There is more detailed information here. It was written a while ago, so might be less relaxant to modern hardware, but still worth reading:
