[SFOS Browser] Solving the browser memory issue

jojo · 6 May 2023 15:36

So I started running the tests, current setup is:

Xperia 10II, build 4.5.0.19
Using the 4G to access internet (in case that has some influence).
Browser has 0 active tabs.
Only open apps are settings and browser.
Browser is still default config, no change in the about:config.
I installed Memory watcher | OpenRepos.net — Community Repository System following @karry 's tutorial Sailfish OS and memory :: karry.cz to check my peak memory usage.

I accessed the website Visual Studio Code March 2023 which has a surprising one shot one kill effect and always kills my browser when opened. It’s my first time ever visiting this specific page.

Bellow my “journalctl -f”, i pasted the “full” log here: Framapad annuel

As you can see I open the browser (which previously crashed) at 17:09:13:

Mai 06 17:09:13 Xperia10II-DualSIM dbus-daemon[5957]: dbus-daemon[5957]: [session uid=100000 pid=5957] Activating service name='org.sailfishos.browser.ui' requested by ':1.5520' (uid=100000 pid=25032 comm="/usr/libexec/mliteremoteaction org.sailfishos.brow" label="u:r:kernel:s0")

And 4 seconds later lowmemorykiller is killing stuff:

And finally the browser…

At 19:09:07 (so before re-opening the browser after it crashed), my memory was shared between:

This setup is:

Xperia 10II, build 4.5.0.19
Using the 4G to access internet (in case that has some influence).
Browser has 1 active tabs (Visual Studio Code March 2023)
i disabled android and my emoji keyboard which was spamming the logs when there was a crash.

Full journalctl logs are here: Framapad annuel

By the way, this error:
binder: 2795:2795 transaction failed 29189/-22, size 32-0 line 3096 is when I hold the CTRL key before doing a CTRL + c

In this scenario I closed the browser, ran memory-peak --measurement-time "2023-05-06T17:47:30 before opening:

Hi all. Is here some guru who knows Linux memory management? I’m author of memory watcher tool, I read many sources about memory, but still cannot say properly how available memory is distributed. Problem for me is this computation: anonymous memory of user-space processes + slab + free value + buffers + caches + swap cache is usually less than total system memory. What allocator owns it? Do I overlook some value?

poetaster · 9 May 2023 14:30

It’s a lot of work, but when analyzing memory usage in the past, I’ve used pidstat for pid level memory usage logging. It’s in the systat packages, usually. I did run it on SFOS. pidstat(1) - Linux manual page

Seven.of.nine · 13 May 2023 05:49

I found something new that seems to help:

apz.autoscroll.enabled: off
apz.disable_for_scroll_linked_effects: on

edit: browser.cache.disk.max_entry_size: 4096 → 1024

I can’t imagine that a max. entry size of 4096 is good while the cache has only 1024 in size by default.

feedback is very welcome!

jojo · 13 May 2023 16:14

I’m trying that tomorrow, and also your tip from the other thread

thigg · 13 May 2023 21:09

Does anyone have an idea how we can benchmark this? maybe select a few sites and do a few testruns from a clean state?

If we had a testprotocol, we could get an objective insight into what acutally helps.

DrDweeb · 14 May 2023 14:32

FWIW www.bangkokpost.com will crash the browser every time today on my 10iii 4.5.0.19

Seven.of.nine · 14 May 2023 14:40

Works fine at the modified Volla.

edit: All quiet on the Mekong front but unfortunately Chiang Mai tourism hit by smog.

DrDweeb · 14 May 2023 14:56

I went to your post about changes you made via about:config

Sadly, when I entered this in my browser, the result was not encouraging. There was no obvious way past this

Edit: There is an invisible “Accept” button on the right of the top bar. Tricky.

DrDweeb · 14 May 2023 15:02

“edit: browser.cache.disk.max_entry_size: 4096 → 1024”

On my 10iii this value is set to 40960 as is the …free_space_soft_limit

attah · 14 May 2023 15:14

That’s a swipe-to-accept like all the other dialogs throughout the OS. Sure, you can tap it, but that’s not how it’s meant to be used.

Works fine on mine. No settings changed, just a basic hostfile block in place - not that i think it matters.

DrDweeb · 14 May 2023 15:31

It’s also meant to have text on it … and unless you are running a 10iii on 4.5.0.19 your experience isn’t that relevant

attah · 14 May 2023 15:34

I am.

DrDweeb · 14 May 2023 15:36

Strange.

My setup is bog standard with no tweaks of any kind as far as I remember.

Hostfile blocks can make plenty of difference. Try turning it off and see if it alters behaviour

attah · 14 May 2023 16:23

That didn’t make any difference. That site doesn’t seem to have very many ads.

teracube · 14 May 2023 17:00

I have changed Browser to ANGELFISH …all OK!!!

DrDweeb · 15 May 2023 03:59

I charged up my old XperiaX with 4.4.x on it, and it loaded OK, but much slower, obviously. This is pretty strange.

Update: It worked yesterday on the 10iii after the headline changed. Hmmm, very strange

jojo · 15 May 2023 18:27

So, same benchmark as before:

Xperia 10II, build 4.5.0.19
Using the 4G to access internet (in case that has some influence).
Browser has 0 active tabs.
Browser is still default config, no change in the about:config.
Browsing: Visual Studio Code March 2023

First test was following @Seven.of.nine tip on another thread:

The scenario:

I opened DeadBeef Silica
Played one song for a few seconds
Opened the browser

Spoiler alert, did not work. The browser crashed with the music app with it:
