Memory used 460M idling on Sparky3.4.1X64

Thanks to the 3.4.1 release.

I prepare USB flash with Linux dd command.
No issue to boot in UEFI mode, install in UEFI and boot it.  :)

A quick check on memory used...
I am not sure why it is so high..

using htop, just idling, I see around 460M used
same as in free -h

wayne@sparkyx64:~$ free -h
             total       used       free     shared    buffers     cached
Mem:          3.8G       1.2G       2.6G        62M       109M       649M
-/+ buffers/cache:       464M       3.3G
Swap:         7.9G         0B       7.9G
wayne@sparkyx64:~$



if I just run iceweasel, I would add to around 640M, with two tabs open on just sparky and another forums.
wayne@sparkyx64:~$ free -h
             total       used       free     shared    buffers     cached
Mem:          3.8G       1.4G       2.4G        66M       110M       658M
-/+ buffers/cache:       637M       3.1G
Swap:         7.9G         0B       7.9G
wayne@sparkyx64:~$


I think 200M added for iceweasel is typical.


I am used to run Debian xfce, 32-bit, on idling, memory used range from 110M to 160M.
here, Sparky xfce 64-bit, on idling, memory used around 460M.. very high compare to Debian7.x

it does not appear as 'light' when it idles around 460M..
I remember also when running live mode it is something like 2xxM..

My question:
On installed OS,  is 460M idling considered typical?
How do I figure out what are using so much memory?
are there some 'hidden processes' that consume unnecessary memory?

Thanks

All 64 bit systems use more power than 32 bit for sure.
I am not sure how much more 64 bit efi system takes than 64 bit bios.
I will make tests and publish my results.

Hi pavroo,

I understand 64bit would take more mem footprint, but 460M idling is quite a surprise..


Here I boot into two other Debian /Debian based distros for a quick check

1. Debian-Testing-64bit_UEFI-gnome

Idling around 272M

Swap:         7.9G         0B       7.9G
wayne@debuefi:~$


2. Debian based, theme-ix,  XFCE, 64-bit , UEFI, it was supposedly emulating xubuntu but based on Debian.

Run firefox with one tab opens, mem used around 255M, htop reading about 237M
this sound more like what is 'typical'...I think so.

something must have eaten memory on sparky xfce..
just do not know what they are..


EDIT..
3. Debian 7.6 Xfce 64-bit, UEFI
idling around 159M
open iceweasel, one tab.. around 292M

I've checked it on my machine - it uses 200 MB of RAM about.
Can you check what process consumes so much power?

Did a check on md5sum.

I used torrent, I thought it is better in having error check.

from the download page
31c1ddde82661af8dd5bdcd3ce7b7a64  sparkylinux-3.4.1-x86_64-xfce.iso

from the file downloaded into my computer
wayne@hp8000:~/Downloads$ md5sum sparkylinux-3.4.1-x86_64-xfce.iso
31c1ddde82661af8dd5bdcd3ce7b7a64  sparkylinux-3.4.1-x86_64-xfce.iso

so they matched.

now i dd the iso to usb flash again.
then, boot into UEFI mode, select the third line to check integrity..
end with this error, module ehci-orion not found in modules.dep


captured in image, not sure if this matter..
