What is the typical memory usage of a GuixSD system?
I can't seem to get mine below 5GiB, according to top.
This is when I stop Xorg and most system services, including networking 
and such, and just log in to a plain terminal with nothing but top 
running. Is this normal?
The numbers listed per process in top don't even add up to that, but it 
reports the total being high. Also, icecat uses a 1000m and 
gnome-terminal uses 500m.
This seems wrong to me, but I'm not sure. In my session right now it is 
reporting over 14GiB of memory use. I don't know why it should be so 
high.

There's no such thing as a typical system. It depends on what you run,
300 open browser tabs will lead to more RAM used for example.

I'm watching a video, write in an IRC client, and run some other
background applications and I'm at 3.5 GiB RAM.

I understand. I didn't mean to leave that as the whole of my question.
I elaborated more on my situation. I have stopped Xorg, networking,
and the guix daemon. I was still at over 5GiB.

So that seems to confirm my suspicion that something is wrong with my 
system.
I am way over that mark with basically nothing running.
As well, I checked another system I have that runs Arch Linux and I 
found that
with full gnome-desktop and several extra services running, it is around 
4GiB.

I was wondering if it was just something strange about the Guix 
binaries.
Anyway, I'm just looking for ideas. I know it's a pretty vague problem.
It just makes me wonder if my system is compromised somehow.

I think I will try a fresh install to see if it changes anything.

I have a headless system with 3 GiB RAM total. I'm currently compiling
the Linux kernel and GCC, and ~900 MiB are actively being used by
userspace processes, with the remainder filled with assorted buffers and
cache.

This is rather high - are you sure that you don't count cache into
this?

What is in /proc/meminfo?

Ugh. This with a full blown Gnome desktop?

It doesn't sound normal to me. I'd expect Gnome to boot with about 1 GiB
RAM usage.

Depends how many tabs you have opened but yes, IceCat/Firefox/Any
browser are very memory hungry.

Using the minimal desktop environment (ratpoison) with GuixSD I'm
booting with RAM usage of about 100 MiB.

Full-blown GNOME Desktop shows in GNOME System Monitor as consuming <390
MiB of RAM. Opening the arstechica.com Web site in netsurf-gtk makes for
a total of <490 MiB.

Note that top can distinguish between „readily reclaimable“ memory and
memory that is not „readily reclaimable“, which AFAIK is what is
actually important. See the top man page.

Florian

Thanks for the feedback on this. I think it was just my mistake.
This is what I was looking at: GiB Mem : 16.6/2.929
After using 'free', which gives more reasonable output, I think top is
reporting a percentage. I never realized that, and it seems unintuitive,
given the units it displays, but this is not a Guix issue, just my own
mistake in what I was reading.

I think it is only unintuitive because this was changed in a recent
version of top. You can press 'm' twice to display the memory values
instead of percentage, or '?' to learn about the different toggles.
