Ever since I first installed Ubuntu I’ve added a line [vm.swappiness=10] in /etc/sysctl.conf to adjust the frequency the system MIGHT look to use swap.
Thus far in UM 16 fresh install I haven’t inserted this line. I’ve noticed the UM 16 seems more responsive than Ubuntu 14 {using gnome flash back] on the same hardware. So my question: Is there a log that contains information about swap or memory usage over time?
My thought is to apply this tweak after I’ve examined appropriate data
There’s a built-in tool called vmstat that might be appropriate, though it won’t show nice graphical stats.
You can log the output into a file for later review with something like:
vmstat -na 5 >> ~/Desktop/vmstats.log
(It will collect the stats every five seconds, delay to be tweaked to your liking.)
Cheers
Thanks, I was hoping to scrub some existing log about memory. I’ll keep this in mind 
Also possible to tune vfs_cache_pressure with swappiness.

and also zram option

Zram-config can be installed from our software repositories.
How much ram do you have?
Thanks for the links and reply.
Dell Studio 1749 laptop 8 GB Core i3 @ 2.13 GHz - general use - this is item really in question
HP tower 12 GB Core i7 960 @ 3.2 GHz - I edit music, photos, and videos so I have plenty of swap.
Just installed 32 bit on Acer Aspire 1 nav50 1 GB Intel Atom 1.66 GHz
My interest is #'s 1 & 3
Unless this is a production computer with software requiring a lot of ram, I would run noswap. You dont need it.
Easy to turn on/off in terminal.
Code:
sudo swapoff -a
