The output is easier to read if you use CODE tags instead of QUOTE tags. Also, use the -h switch (human readable) with df. (df -h)

So, would you kindly redo the command as df -h then copy and paste between CODE tags.

What the dickens is tmpfs?

If I interpret this correctly, it's using twice 4G! For what?

Tmpfs is a file system which keeps all of its files in virtual memory and there is not wrong in your case.

Did you enabled DRM content playback in Firefox?

In the General panel, scroll below to the Digital Rights Management (DRM) Content section.
Tick the check mark next to Play DRM-controlled content.

I used quote because every page tells us not to use code.

Yes, I have enabled DRM.

Code:

tmpfs           784M  132K  783M   1% /run/user/1000

What are those tmpfs's with 9G of my precious memory? I only have 8!

Where did you see 9G? If you have only 8 G of memory ram you can disable tpmfs on /tmp. This is the only folder that can allocate definitely memory ram and in your case it is 3,9 GB. Check your etc/fstab and if it is the case you are going to see something like this there :
tmpfs /tmp tmpfs noatime,mode=1777 0 0

Comment with # or erase the line.

"only 8 G of memory"?

I've always thought that was a lot! Is memory hogging by apps inflating as fast as that?

Should I double it again?

In fact, I used to have a partition which was mounted as /tmp. Is that not done any more? I'll have to look for it. Without tmpfs or a partition, I'm afraid it will start gnawing on my root volume.

**joneall** · Oct 28, 2024, 01:51 AM

I have now added an honest-to-gosh partition for /tmp, but it still wants to use a tmpfs.

Code:

No worries. I have a system with 32 GB of memory ram. Most of the times it used 4 GB of memory ram. Most of the times it doesn't even use swap. Only in special cases it use to use more than 5 GB of memory ram.

More memory ram is important of course, but it depends of your usage. Video or photo edition works better with more memory ram for example.

I could see you are afraid about tmpfs. Look, tmpfs is a file system that reside in memory ram. In the specif case of /tmp you can use tmpfs on it, and temporary files will reside in memory ram. In the other way it will be on the hard disk os SSD or even other kind of storage.

Do you really need the temporary files to be in memory ram? Most of the times ... No. But...again, it depends of your usage.

For example: i have a specific program that use /tmp when transfer a lot of files. So, i decided to use tmpfs on /tmp because memory ram is faster compared to the hard disk. I checked the usage and choose 8 GB of my memory ram to be used on /tmp as a tmpfs. But like i said only in special case, because most of the times it use 40 MB. In my case, i have 32 GB, so i decided to allocate 8 GB for that special case.

In the case of /tmp using tmpfs it allocate by default a half of memory ram. In your case 4 GB. You can change this on etc/fstab , specifying a number for it. You need to monitoring what you really need if you want to use tmpfs on /tmp, because if tmpfs is not enough it will going to use swap.

So, the question is : Do you really need tmpfs on /tmp ?

Look at your /tmp now. Since you remove it from tmpfs on etc/fstab it now resides on /dev/sdb4 and continues to use 1% . And what filesystem? That you choose for your system like ext4, btrfs, or any other.

You can't and you don't need to do that. Dont worries about the others tmpfs. The system need to use them in this way.

Tmpfs is a file system which keeps all of its files in virtual memory.
Everything in tmpfs is temporary in the sense that no files will be created on your hard drive. If you unmount a tmpfs instance, everything stored therein is lost.

tmpfs puts everything into the kernel internal caches and grows and shrinks to accommodate the files it contains.

In your case look at the Use% ... Only 1% of memory ram.

If you want to check the total amount of memory ram consumed by all tmpfs filesystems go to the / proc/meminf and look at the Shmem field. You will be surprised that most of the times it uses a low amount of memory ram.

Ok, I doubled my RAM; my motherboard is maxed out now with 16 GB. Everything works ok, but I still don't understand why the boost in memory usage by Firefox and Chrome with 6.2.
