redshift-gtk memory consumption?

[saamalik]

Memory consumption:

• redshift: 444 KiB
• redshift-gtk: 15.6 MiB

15 MiB seems a little excessive for a tiny panel widget, but is this expected? If so, please junk this bug.

Running:

• Arch
• Gnome 3.12
• Redshift 1.9.1

I observe 13,8 MB.
Python itself takes 3,4 MB. How much does small graphical programs like this usually take?

[maandree]

I have looked at a few python-based programs and whilst it is quite a bit, it is not that much more that other programs.

I'm not so sure about this, on my box I'm using;

87.14 Mb python3 /usr/bin/redshift-gtk

[maandree]

How long do you have to run /usr/bin/redshift-gtk before it comes to this size?

These are my specs;

Slackware 14.1 x86_64
redshift 1.9.1
python3-3.4.1

I rebooted to test this, as soon as I logged into Openbox, which is just with startx, I ran this command to check the MB of each process;

ps -eo size,pid,user,command --sort -size | awk '{ hr=$1/1024 ; printf("%13.2f Mb ",hr) } { for ( x=4 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }'

And this is the output;

85.63 Mb python3 /usr/bin/redshift-gtk

So to answer the question, redshift runs in the upper 80MB as soon as it starts for me, which seems a little on the heavy side, hmm

[maandree]

Yeah. I have no clue what could be that cause.

[saamalik]

After three days of running, redshift-gtk memory consumption is up to 24.5mb. Looks like there is a slight memory leak as well.

[maandree]

There might be a memory leak in a library redshift-gtk uses, at least I see that as more likely than redshift-gtk itself (although that is still a possibility).

@saamalik looks like I have a bigger memory leak, hehe

maandree, ok...

Well hopefully this is something Jon can look into and fix...

[manhtukhang]

OMG!
298.65 Mb python3 /usr/local/bin/redshift-gtk
0.40 Mb /usr/local/bin/redshift -v

[maandree]

redshift-gtk uses Ubuntu's AppIndicator if available and otherwise traditional xembed.
Perhaps it is specific to one of them. What are you guys using?

298 damm ouch! :(

Well as I mentioned I'm using Slack...

Currently we are keeping every output line from the redshift process buffered in redshift-gtk which is probably a bad idea. I can't see any reason why we would want to do this so I'm going to guess that this was probably added for debugging and was just never removed. This should be a quick fix removing those 2-3 lines and will most likely lower the memory use when redshift-gtk is run for weeks. (Note that this is not a memory leak in the technical sense.)

Regarding the memory usage at startup, the numbers that you report seem completely reasonable. However, it should be noted that there are a number of ways of measuring memory usage and without specifying how it is measured or at which tool was used to measure memory usage, the number is not very useful. See this article (http://virtualthreads.blogspot.com/2006/02/understanding-memory-usage-on-linux.html) for a good overview and also an answer to why very simple GUI programs can seem to take up a lot of memory.

Ahhh nice to hear, look forward to this quick fix... :)

Thanks jonls
