Dear Michael,

It was not my intention to offend you. Sorry for sarcasm.

I don't believe that CPU slowing down due to no activity will be felt by
a desktop user, because even moving a mouse will cause CPU frequency to
spike. And a busy computer (OP has stated that CPU has a constant use of
around 30%) will have frequencies high anyway.

That doesn't sound right.  128 MB of RAM?


It is buffer size of the hard drive with shingled magnetic recording.

Do you happen to keep the Web Developer Tools open?  Or console logs
set to persistent?  Those will keep lots of things in memory just in
case you need them as a developer trying to debug an issue.
Generally, if I notice my memory usage going up, I will be sure to
close the Dev Tools and reload the tab a couple of times.  Then,
eventually, the JavaScript garbage collector will kick in and start
releasing the items the Dev Tools have stopped tracking.

FF also has built in performance tools that can be used to determine
what may be using resources.  Menu -> More tools -> Task Manager (aka,
shift-esc or about:processes).

Nothing Debian specific here.
https://support.mozilla.org/en-US/kb/task-manager-tabs-or-extensions-are-slowing-firefox#w_task-manager

It may be leaks in JavaScript code running by particular web pages, not 
Firefox fault.


Firefox has the "restore previous session" feature. My expectation is 
that it should work more reliable than "kill -9". The latter may cause 
inconsistency in data saved to disk. I see nothing wrong with "close 
window" (Alt+F4). An alternative is "quit" that closes all windows at once.

Not necessarily, no.  It may consciously decide to hold on memory that
was used in the past in order to avoid having to re-allocate and
re-initialize it next time.
Some of that is simply "the cache", but there are all kinds of things
like that.

A leak would be if the amount of memory use increases each time you
visit a given page, even though that page always has exactly the
same content.

There's something. You have a 4 x 1.8 GHz CPU but it's actually

CPU is idling and there is nothing to do, I don't know why you want to

all the way to 0.80 GHz is actually great, that is definitely conserving

Here's another example:

Oh look my Ryzen is broken because it's only delivering 2800 MHz instead
of advertised 3800 MHz, yes? No. It's power saving because there is
nothing to do, processor is not busy, so frequency is scaling down. This
is all by default, no tweaks required.

(note: all on one line)

I'm fairly certain that when you say that "the system blew up", you do
not mean that it literally exploded. Do you mean crashed, or slowed
down considerably?

Unfortunately modern browsers as a rule are quite memory-hungry. My
current Firefox instance (same version) is using ~1GB of memory, and I
don't even have a lot of tabs open or have had it running for
particularly long. Still, 7-8 GB of RAM (as indicated in your response
to Greg) and only half of it in use should be enough for most everyday
needs.


> The system uses 30% CPU, 265 Process, 50% memory and swap 9%.

None of those are particularly high; and you certainly aren't
bottlenecked on any of them. It's normal to see some swap usage even
if you aren't actually using all RAM, especially if the system was
under memory pressure earlier (since the most recent reboot).

Searching for "Toshiba L200" doesn't really tell me anything about
your computer, but since it has a 1 TB 5400 rpm HDD, I would guess
that your computer is not the most up-to-date model. That's fine;
Linux in generally tends to be a good choice for slightly older
computers. However, if you have a processor with few cores (maybe even
just two or four cores), it's entirely possible that something is
bottlenecking on a _single core_. Given your figure of 30% CPU usage,
I wouldn't be surprised if your system has a 4-core CPU and some
single-thread process is bottlenecking on single-core performance.
Depending on the exact tool, you'd see either a single core fully
utilized and all others idle as 25% utilization, or as 100%
utilization (with all four cores being fully utilized then being shown
as 100% or 400% CPU usage, respectively).

Could you show us the output of these four commands executed in a
terminal _while you're doing something which you feel is slow_?

grep -m 1 -e '^model name' /proc/cpuinfo

grep -e '^cpu MHz' /proc/cpuinfo

free -m

grep -c '^processor' /proc/cpuinfo 

That will tell us what CPU and how much memory and swap your computer
has.

That doesn't sound right.  128 MB of RAM?  I think you must have more
than that, or else you wouldn't have been able to run all those programs
*at all*, never mind worrying about performance.

Firefox, in every version I've used so far, appears to have memory
leaks. If I kill it, not by clicking its little "X" or Alt-F4, but with
"kill -9", so that it reopens everything when I restart it, my memory
usage immediately drops by 75%. Then it creeps back up.
