Xfce4-Cinnamon RAM statistics

Postby Eyeteeorg on Tue Dec 25, 2012 4:23 pm

I ran the free command on both my main Cinnamon GUI and the Xfce4 I added through Package Manager and this is what I came up with:

Cinnamon:

Code: Select all
             total       used       free     shared    buffers     cached
Mem:       2051000    1488352     562648          0      42540     701656
-/+ buffers/cache:     744156    1306844
Swap:      3145724          0    3145724

Xfce:
Code: Select all
             total       used       free     shared    buffers     cached
Mem:       2051000    1437432     613568          0      70296     968400
-/+ buffers/cache:     398736    1652264
Swap:      3145724          0    3145724

Savings = Xfce used - Cinnamon used = 398,736 - 744,156 = -345,520
Savings percentage = Savings / Total = 345,520 / 2,051,000 = 16.84%

Considering that Cinnamon chews up about 35% of RAM, the 16.84% savings in RAM use on my system is pretty significant.

Does anyone else want to post their own numbers?

The comparison isn't really fair, now is it. You must have been running more programs on Cinnamon :) Here is the output of the free command on my Cinnamon installation:
Code: Select all
             total       used       free     shared    buffers     cached
Mem:      16154196     762020   15392176          0      59672     344400
-/+ buffers/cache:     357948   15796248
Swap:            0          0          0

What do you know, using 10% less memory than your Xfce session :D This is on a 64-bit install BTW, which is relevant as 64-bit uses more memory than 32-bit. If you are still running Cinnamon 1.4, recommend you upgrade as the current Cinnamon release (1.6.7) is much more efficient with RAM and CPU.

That's fascinating, Vincent. I still have a very basic install as I haven't optimized my system yet. Perhaps your system is optimized and that's why your Cinnamon has such a tiny footprint.

My original install DVD was the Mint 14 x64 Cinnamon 850-meg one. I could have messed things up by creating separate /, /home, /var and /tmp partitions, but I don't see how.

Can you remind me of the CLI input that returns my current version of Cinnamon, preferably from the Xfce environment so I don't have to relog? If an upgrade is called for, I definitely want to do it. Like everybody else, I need my RAM available for applications rather than chewed up by the GUI.

No worries, on Linux Mint 14 you will be using Cinnamon 1.6.7. When not running Cinnamon, you can check the installed version with:
Code: Select all
dpkg -l cinnamon

It should return something similar to below, with the last line showing I'm running version 1.6.7 for nadia (=Linux Mint 14).
Code: Select all
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-=================================
ii  cinnamon       1.6.7+nadia  amd64        Cinnamon desktop

And sure, I've optimized my system somewhat but also added to it. A clean install of Linux Mint 14 Cinnamon probably uses a little less memory than my system. Optimizations I did that save a bit of memory were disabling of the Avahi, Bluetooth, Modem-Manager and Samba daemons and removal of the VirtualBox guest additions and utilities. That's not a 400 megabyte difference though, and I disabled them not to save memory but to improve security :wink:
