[Software] Nemo is slow and takes a lot of ram

#1 Post by larienna »

I have just configured Cinnamon and when using the Nemo file manager, navigation is extremely slow. I take 5 seconds to move between folders even if there is a very small amount of files in that directory. Right clicking also take 5 seconds. At the same time, nemo take 500 megs of ram, which exceed firefox. Other file browser like dolphin and thunar consume 1/10th of that amount. I am running on an m2 SSD, so it should not be an hardware issue.

I am considering that both issues should be connected. I tried to fix one or the other without any success. Things I have tried so far:

* Reinstall gvfs (no effect)
* Disable plugins ( I only had one, so it had a minor effect)
* Disable thumbnails (minor effect)
* Clear the cache using "rm -rf ~/.cache/thumbnails" (no effect)

The version of nemo I am using is 5.6.4

Is there any other solution?

Description: File manager and graphical shell for Cinnamon
 Nemo is the official file manager for the Cinnamon desktop. It allows one
 to browse directories, preview files and launch applications associated
 with them. It is also responsible for handling the icons on the Cinnamon
 desktop. It works on local and remote filesystems.
 .
 Several icon themes and components for viewing different kinds of files
 are available in separate packages.
UPDATE: Here is a copy of the process info

Code: Select all

$ ps -aux | grep "nemo"
ericp       1781  0.0  0.1 457080 33312 ?        Sl   Dec05   0:00 nemo-desktop
ericp       7038 15.6  1.7 1628888 553580 ?      Sl   02:10   0:10 nemo
ericp       7189  0.0  0.0   8864  2168 pts/0    S+   02:11   0:00 grep nemo
System monitor shows 502.1 Meg for nemo, and 486.3 meg for Firefox. Beating firefox in matter of memory consumption is an achievement in it self. :D

I don't use nemo, maybe you should do a bug-report.

This is what I am currently doing, I am using Thunar, but I know thunar stability could be flaky, in some situation it could crash.

I think there have been bug reports in the past since I found many threads about this issue, but the causes seems very diversified.

Fun fact, I decided to try using Caja because Thunar could not allow me to right click on a empty area without freezing. Clicking on "File" had the same effect. Probably due to the position of the moon in the sky.

It happens that Caja was taking 1 gig of ram and was continuously consuming more and more ram.

I would suspect something on my system is making those 2 file browser go wild.

I guess we are back to the command line.

Well, if you can use some other pc/laptop, perhaps running memtest for a few days.

The computer is brand new, I doubt it's an hardware issue.

I'll try to launch those software under a different DE.

A few things I would try:

Running nemo from the terminal and seeing if that provides any extra info.

Try running the following as well:

For load times

Code: Select all

nemo -q; NEMO_BENCHMARK_LOADING=1 nemo  /path/to/some/directory
For debugging

Code: Select all

nemo -q; NEMO_DEBUG=all  nemo --debug /path/to/some/directory

It would not be the first time memory chip to have bad solder, etc,

I went back into KDE plasma

Nemo still takes 500 meg of ram.
Caja is now at 1.3 gig and keeps increasing.

I tried in mate

Nemo remains at 500 meg of ram.
Caja is currently at 1.9 gig and keeps increasing. Not really sure what is the limit. It's now 2.4 gig.

Is this a default install or have you changed any parameters regarding swapiness or disk caching.

What does this report?

Code: Select all

free -m
And if you run this what happens?

Code: Select all

echo 3 | sudo tee /proc/sys/vm/drop_caches

See if it is possible to use a different theme? Also do you have network shares, NFS/Samba/ZFS/etc connected? See if disabling those helps to improve the speed.

Also how much is the free space on your M.2 disk? Will it be possible for you to execute the following command and give the output over here? Please enclose the output within code brackets

Code: Select all

Re: [Software] Nemo is slow and takes a lot of ram

#16 Post by larienna »

I do not have network drives. The installation is relatively recent, so there is a lot of free space. I tweaked a lot of ramdisk, maybe that is the source of the problem. But having 32 gig of rams was the whole purpose to create lof of ramdisks:

Re: [Software] Nemo is slow and takes a lot of ram

#17 Post by larienna »

I think I used in memory compressed swap, to avoid swapping on the SSD

Code: Select all

 $ free -m
               total        used        free      shared  buff/cache   available
Mem:           31273        4095       24618         193        3202       27178
Swap:           3127           0        3127

Code: Select all

 $ echo 3 | sudo tee /proc/sys/vm/drop_caches
3
I ran all those commands without Nemo or Caja Openned.

If you run the free command again just after the command starting with echo is there any difference? I think you should do it with Nemo running too.

I launched both commands before nemo, and after nemo. Here is the log

Code: Select all

ericp [~]
 $ echo 3 | sudo tee /proc/sys/vm/drop_caches
3
 ericp [~]
 $ free -m
               total        used        free      shared  buff/cache   available

 ericp [~]
 $ echo "I started nemo"
I started nemo
 ericp [~]
 $ echo 3 | sudo tee /proc/sys/vm/drop_caches

 ericp [~]
 $ free -m
               total        used        free      shared  buff/cache   available

Swap:           3127           0        3127
Weird, I do not see a difference. Here is the PS command:

Code: Select all

 $ ps -aux | grep "nemo"
