Initial stats & comparison page draft #129

MichaIng · 2021-06-17T15:01:36Z

We may enhance the script a bit, e.g. it makes sense to merge root and boot disk usage, check swap file size before removing it and to have it optionally creating the HTML block required for page? 🙂

Styles in <head> will move into styles.css, but while experimenting it's easier to have it in the header for now.

MichaIng · 2021-06-17T17:24:52Z

Ideas from feedback:

Highlight/colour smaller (better) value, green vs red or similar, which suites colour scheme
Remove commands, instead make an own tile containing the commands, used for each stat, and the script as well
Bar charts and/or percentages to visualise comparison better
Make tabs OS selectors with each multiple hardware tiles
Use or merge OS/distro logo into tiles
Sort stats by importance

from: #129 (comment) ToDo: Bar charts to visualise numbers

MichaIng · 2021-06-24T18:25:42Z

Second feedback round:

Add additional column between "DietPi" and compared OS for "DietPi / " percentage as DietPi divided by compared OS.
Use a slightly brighter red for the "looser" and the code tags.
Add distro logos
Add all data we do already have

Bar charts are added in a dedicated round, as we need to think a little more about how to add them nicely.

and make code+looser red a little brighter

and remove obsolete :visited button style.

and increment stylesheet version which contains the required styles.

MichaIng · 2021-07-15T18:52:23Z

Ready from my end. Please have a final look (test URL), also note the additional button in the features section below the title.

Joulinar · 2021-07-15T20:55:13Z

do we need an additional comparison for RPi OS 64bit?

MichaIng · 2021-07-16T09:34:54Z

Would be great indeed. Pinging @fpetru and @StephanStS here, so there is no doubled comparison done. I suggest the first one who actually starts doing this leaves a post here to inform the others 🙂.

Joulinar · 2021-07-16T09:43:03Z

I can do that. RPi3B+ or RPi4b 8GB?

MichaIng · 2021-07-16T10:55:04Z

RPi 4 would be better I think, as this is what most users nowadays have.

/tmp is not a tmpfs, which is bad since volatile files lead to disk I/O.

/var/log is not a tmpfs, which is bad for disk I/O, but logs are preserved on system crash.

This image comes with an SSH server pre-installed.

/tmp is a tmpfs, which is good to reduce disk I/O.

/var/log is a tmpfs, which is good to reduce disk I/O, but logs are lost on system crash.

This image comes with an SSH server pre-installed.
The script was executed from within an SSH session, which increases the process count above by one, compared to a local console session.
Assure to run the script via SSH as well on other systems you want to compare.

MichaIng · 2021-07-16T11:27:12Z

switched to Static IP. Boot duration changed from 17.836s to 9.852s 😉

Since RPi OS most likely uses DHCP as well, I think it's fair to compare against our unmodified image with DHCP, what you think?

And to avoid two additional processes + their memory usage, could you run those test with the script sourced?

curl -sSfLO https://raw.githubusercontent.com/MichaIng/hacks/main/dietpi-distro_comparison
. ./dietpi-distro_comparison

Yes it reboots on first execution intentionally to assure that everything is at a clean state and new kernel loaded after APT upgrade, in case.

Joulinar · 2021-07-16T11:28:56Z

ok will run the script again, flashing RPi OS 64bit atm

MichaIng · 2021-07-16T11:34:40Z

Okay, before you flash back and forth, I think it's fine when you run the script on RPi OS just the same way (curl | bash pipe). Thanks to GitHub edit memory, also the old boot time with DHCP is still there 🙂. Most importantly both distros are tested the same way, whether there is one expected process more or less is then not so important IMO, when it's the same on both.

Joulinar · 2021-07-16T11:36:28Z

I have too many free SD card since I switched to USB boot for my testing devices 🤣

Will run both the same way and update the original post with both results

EDIT
done ✔️
