Not a question, just an observation.

I say that Linux doesn't seem to handle memory well because my laptop
had 8GB RAM (which, frankly, Windows seems to find perfectly adequate
for a similar workload). Under Linux the RAM would fill up and then swap
space would be used. Then the machine would become largely unresponsive
- e.g. taking minutes to switch between windows.

So I upgraded the RAM. It now has three times as much (i.e. 24GB)! But
even so, RAM has still steadily filled up until reaching the full 24GB.
What's more, it's now showing 4.8GB of swap space in use.

Linux swaps out lesser used pages anyway to make the backing memory
available for buffers or cache.

Those people writing memory management are really smart. Smarter than
you and me together. Don't assume them being stupid.

That's not Linux. That's a rogue program with a memory leak...

Likely you're using a system that's configured for maximum total throughput,
not best response time.

Create a file, /etc/sysctl.d/tales.conf with the contents ...
# Reduce applications being swapped
vm.swappiness=1
# Don't shrink the inode cache
vm.vfs_cache_pressure=50

Then run the command "sysctl --system" (as root).

See https://rudd-o.com/linux-and-free-software/tales-from-responsivenessland-why-linux-feels-slow-and-how-to-fix-that
for an explanation.

Yeah.. look in htop for high memory usage. I know Steam takes a lot of
memory.

I say that you are mistaken, and that Linux handles memory quite adequately
(but differently from how Windows handles memory)

Ahhh.... now you describe your problem symptoms. Perhaps, with more
details, we can help you get the sort of performance that Linux can
properly provide.

Sounds like a leaky application, but without more info, we can't help.

To give a counter-example, here's a snapshot of my desktop system's
usage (taken from top(1) )
Tasks: 302 total, 1 running, 301 sleeping, 0 stopped, 0 zombie
%Cpu(s): 0.0 us, 0.8 sy, 0.0 ni, 99.2 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
MiB Mem : 30096.1 total, 25727.6 free, 2156.9 used, 2211.6 buff/cache
MiB Swap: 65536.0 total, 65536.0 free, 0.0 used. 27297.9 avail Mem

While I have more memory than you do (32Gb as compared to your 24Gb), I have
302 processes running and only about 4Gb of memory in use. Of my 64Gb of swap
space, /none/ is in use.

My previous desktop system(s) had less processing power, less memory, and less
swap space, and ran lively, without memory or response time problems.

So, if you want help, how about providing some details.

HTH

Check the swapiness settings.

It uses the RAM as a disk cache - for caching files from the disk and
for caching files to be written when the disk is in use.

There more to it than just the amount of free RAM.

Linux uses otherwise unused RAM for disk cache:

Link - Help! Linux ate my RAM!
- https://www.linuxatemyram.com/

But using swap tells me that something else, not just Linux itself, is
consuming / leaking memory.

See what's using the swap. That's going to be the offending process.

Run `top`
Hit the `f` key to add a field.
Scroll down to SWAP and hit the space ` ` key to turn the swap column on.
Hit the `s` key while still on SWAP to make it the sort column.
Hit the `q` key to go back to the main screen and see what's using swap.

Sounds like some rouge application and not linux. I never had any ram
problems with linux given 4, 8 and now 16 gb of ram and I run firefox and
xfce. Even ran gnome on 4 gb ram and no problems.

To each their own.

As long as their own gets the job done.

I've stuck with top as many systems I've worked on didn't have htop
installed and I never felt compelled to justify why htop needed to be
installed / top wouldn't suffice to the change approval board.

Not a common complaint among Linux users, anyway.

Try using the “top” program to identify the culprit. It lets you list
processes by various criteria, such as RAM usage and CPU usage.

Indeed, though it’s possible that requesting help might have saved him
the cost of 16GB of RAM, wasted time, etc.

Why is it only we IT people that we have to justify the use of
appropriate tools to a board of often non-technical people? No
mechanic ever had to appear in front of a board to justify the use of
spanner and screw driver, right?

No, your analysis is not correct.

You have some buggy application or service that is eating all the
memory. You have to search and hunt for it.

Do you want our help?

I just threw another 16GB of second hand RAM into this machine . The
rogue RAM eater was a combination of Firefox and a Windows VM.

Took almost 5 minutes. Cost less than £20.

Do the simple cheap options first...
