I am not sure how or where I set it, but, from memory, I had set it to 80.
It's a sysctl, so you adjust it like this (as root user) :
# sysctl -w vm.swappiness=60
And you could put "vm.swappiness=60" (without quotes) in your
/etc/sysctl.conf to have it always set to this on boot.
Okay - I did a cat on the file, and found it to be set at 70. I had
believed that I had changed it to be set at 80 - maybe I had done the
command at the command line, and it had not been saved to the file, so
that the next time that the system had booted, the setting change had
been lost.
I have now used vi and edited the sysctl.conf file, and, set it to 90.
and that shows as having been saved to the file.
I have also run the command from the command line, to change the
swappiness to 90;
"
:~# sysctl -w vm.swappiness=90
vm.swappiness = 90
"
However, I am not seeing any change to the swapping.

The main application that I am at present running, is konqueror, running
as a web browser, running multiple windows of it.
Alongside that, I am also running (at present) Ekiga and skype, and,
yesterday, I had a couple of successful video calls via skype, with the
low available memory, although, in one of the calls, the video went
still (froze, bit not pixelated or lost) one or two times.
The slow data transfer rate, and, the slow loading of web pages (often
involving timeouts), is within konqueror.
Within konqueror, I have javascript disabled (malware that javascript
is!), as, amongst other things, javascript unnecessarily, excessively,
ties up resources.
