and it's responsive. I've usually got 20 or more applications open at
once (most just RXVT windows) and reboot about once a week. If I
invest in RAM I expect it to get used. Seems like Linux and FreeBSD
are better about this but I don't use them often. Now I've got 864
free, 25 swapped out (restarted Firefox).
LOL at Linux better about this...........
Fresh Ubuntu 14.04 LTS with updates
user@laptop:~$ free -m
total used free shared buffers cached
Mem: 3819 834 2984 1 3

Swap: 3959 313 3646
user@laptop:~$ sysctl vm.swappiness
vm.swappiness = 10
user@laptop:~$
With vm.swappiness on default 60 even more pages in swap. Only Firefox
with 2 tabs running.
Trying to get open and load some other page result in like ~1 minute
hang of OS where
I can do nothing, not even switch to text console. Adding flash in the
mix result in
memory leak and Firefox eating everything.
Setting swappiness to 0 helps more, but then why is that parameter here
at all?
Why Linux is swapping most used pages even as there's plenty of free
RAM and cache is
total mystery. I'm sure they will come with something clever, like
systemd handling
vm. That will help for sure.
OpenBSD is superspeedy heaven (even in reality) compared to this crap

stay swapped out overnight until I reboot to clear it. The Gimp

Is there any command to cause the swap system to do a HUP or
something
to re-evaluate the situation?

If the data has remained swapped out, it's because it hasn't been
needed
yet. Perhaps its the process memory for a daemon which isn't being
connected to and doesn't need to do anything. Why would you *want*
to swap
that in?
