#262912 — Performance of my computer

From	William Torrez Corea <willitc9888@gmail.com>

Subject	Performance of my computer

How can improve the performance of my computer?

I have problems when I have a lot of tabs opened in my browser, i am using
the libreoffice or playing on Steam. The system blew up.

My browser: Firefox Browser 115.4.0esr (64 bit)
My system: Linux 5.10.0-26-amd64 1 SMP Debian 5.10.197-1 (2023-09-29)
x86_64 GNU/Linux

My browser consumes 655MB of memory and uses 34% of the CPU.

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

I haven't partitioned my hard disk.

I have Toshiba L200 Laptop PC Hard drive 1 TB, 5400 rpm, 128 MB/8MB buffer

Sounds like you want more memory.

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.

What does "free -m" say?

OP might try another browser that is not so resource hungry:
<https://wiki.debian.org/WebBrowsers>.

Sorry to hang this of GW's post. I cannot find the original in my Inbox.

It is buffer size of the hard drive with shingled magnetic recording. 
Otherwise random write performance would be disaster.

It was discussed a year ago

William Torrez Corea to debian-user. How to can make a partition in my 
hard disk ? Wed, 19 Oct 2022 15:22:49 -0600.

Please run the following command and reply with the console session 
(prompt, command entered, output displayed):

# cat /etc/debian_version ; uname -a

What is the make and model of the computer?

What processor does it have?

What memory modules are installed?

STFW "Toshiba L200" I see:

https://www.toshiba-storage.com/products/toshiba-internal-hard-drives-l200/

Replacing a HDD with an SSD would improve responsiveness when booting, 
starting applications, opening and saving files, backing up, imaging, etc..

The kernel and Firefox version specified in the original question
match current Bullseye, so that seems a likely guess.

While that does appear to be console output for the command I suggested, 
your post is incomplete -- you did not post the prompt and the command.


This is an example of what I was requesting:

2023-10-30 15:43:45 root@taz ~
# cat /etc/debian_version ; uname -a
11.8
Linux taz 5.10.0-26-amd64 #1 SMP Debian 5.10.197-1 (2023-09-29) x86_64 
GNU/Linux


Note that I have set the environment variable "PS1" in the shell 
start-up file ".profile" so that the shell prompt provides useful 
information -- date, time, username, hostname, and current working 
directory:

2023-10-30 15:44:35 root@taz ~
# grep PS1 .profile
export PS1='\n\D{%Y-%m-%d %H:%M:%S} ${USER}@\h \w\n\$ '


Providing good context in your posts will make your posts more useful.


> What is the make and model of the computer?


If you answer this question, we can explore options such as upgrading 
the processor, memory, storage, graphics card, etc..

Again, posting the prompt and command would help us understand the output.


Looking up the specifications on the Intel web site:

 
https://ark.intel.com/content/www/us/en/ark/products/75460/intel-core-i74500u-processor-4m-cache-up-to-3-00-ghz.html


That is a 10-year old ultra-low power laptop processor.  It should be 
adequate for light to moderate desktop use, but heavy web sites, heavy 
office documents, and especially games are going to crush it.

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.

Last step: Run command:
sudo inxi -m

And paste the result, then we will know what are your options to expand RAM.

There's something. You have a 4 x 1.8 GHz CPU but it's actually
running at 800 MHz across all cores. 1.8 GHz is already at the slow
end by modern standards but 800 MHz is definitely slow. If you
actually did this while doing something which you felt was slow, it
should have stepped up the frequency.

This _might_ be different on an older kernel but I'm curious what the
CPU frequency governor is set to. Please try:

for policy in /sys/devices/system/cpu/cpufreq/policy*/; do echo $policy ; cat $policy/scaling_governor ; cat $policy/scaling_max_freq ; done

(note: all on one line)

and show us the output.

CPU is idling and there is nothing to do, I don't know why you want to
investigate normal CPU behaviour. This is absolutely normal. Going down
all the way to 0.80 GHz is actually great, that is definitely conserving
power.

Here's another example:

neofetch | grep CPU
CPU: AMD Ryzen 7 5800X (16) @ 3.800GHz [47.3°C]

$ grep -e '^cpu MHz' /proc/cpuinfo
cpu MHz         : 2627.848
cpu MHz         : 2880.186
cpu MHz         : 2660.697
cpu MHz         : 2874.974
cpu MHz         : 2878.375
cpu MHz         : 2879.568
cpu MHz         : 3800.000
cpu MHz         : 2200.000
cpu MHz         : 2200.000
cpu MHz         : 2878.822
cpu MHz         : 2879.274
cpu MHz         : 2824.946
cpu MHz         : 2200.000
cpu MHz         : 2200.000
cpu MHz         : 3596.336
cpu MHz         : 2869.524

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.

Which is why I specifically asked OP to show the output of those while
doing something where OP felt that the computer was slow, _and_
reiterated that exact point in my response which you quoted from.

Please at least actually read what you're replying to before resorting
to sarcasm and assuming that people have no clue what they are talking
about or making suggestions to check.

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.

Firefox doesn't have any memory leaks. It actively uses buffers, cache,
filling available memory. I have Firefox running for days, sometimes
weeks. On slow laptop, and fast workstation PC. Same result, no crashes,
no memory leaks.

Or is it a plugin that leaks (or crap scripts on the sites)?
