Does Kiwix uses more memory as Chrome?

[y1111]

i expected more efficient like a pdf reader or notepad . but this app takes 100-200mb per page it opens , with 2-4 tbas its already more than a GB
for compare thats how much chromium or ff browsers take per tab in wikipedia , but its also full featured browser much more complex.
and the browser even have the task managers in with i can select and kill some tabs to release ram
for compare too , in simple "links graphics" browser (without js) it takes a mere ~10-15mb per tab (the same pages) (with images)

Considering that at the core, it works exactly like a browser... not a surprise the meomery consumption is the same. All of this is manage by Qt anyway, we have no way to control much memory usage there.

can this browser that qt make be configured ? like disable js ? this probalby would make it smaleer and faster.
i just oipened to see in k-meleon browser - simpler but it have js and its enable . and from opening at 80-85mb it goes only to 95-99mb so about 20mb more for the wioki page, and with js enabled (i even open 2 more pages and only 20-30mb more in ram)

and it seems it doesnt even release the memory back when closing tabs . i just looked the app is still opened here in backgroundand just checked in taskmngr it takes 800MB , just with 2 tiny tabs barely 1 image.

then i click in some link open 3 tabs total 5 tabs only it takes 1166MB .
look even comparing to browsers , opera is opened with some 50-70 tabs taskmgr show 43 processes an this all taking only 1882MB
(also opera have some 30-40 separeta processes half less 10mb and some 10-50 3 200~mb . so lets say a GB more even 3GB for ~60tabs)
really inefficient, not scaling well

i see here #1244 (comment) u say will move to qt6 . will this make it more efficient is this memory use ?
and the app is lika a browser made in qt , is it ? any links or how it works and details . to help me or newbies wanting to contribute to understand faster

that seems interesting https://www.reddit.com/r/browsers/comments/mqe9su/i_am_making_an_ultralightweight_web_browser_for/

All of this is handled by https://wiki.qt.io/QtWebEngine, which is basicaly a Chromium in Qt. I don't think moving tomQt6 will change anything fundamental. This is so intricated in Qt that we can not change this. Closing this issue, are I see nothing which can be done.

@kelson42 I don't think that such tickets should be closed based on pure guesswork without actually investigating whether there is a problem that is in our area of responsibility.

[kelson42]

@veloman-yunkan To make an investigation somthing should be clearly buggy... or at least suspicious. I see nothing in this report which let me think something does not work as expected. Do you? A clear comparison with Chromium showing that for the same content, the memory consumption is widely higher would be such of a clear hint for example that something is wrong.

This may be wrong assessment, but at least it has to be looked into.

@y1111 Would you be able please to provide such a benchmark with all the details so a dev could try to reproduce it (when something is clearly wrong)?
