@sphera We're talking about Service Worker Cache here. If you do not have concrete, specific advice for avoiding Service Worker cache, please DO NOT give advice that will not solve anything and only adds confusion.

I have deleted your off-topic posts and related replies. Please do not derail topics with useless remarks.

totally comfortable with regedit, but feeling now like I have opened a big can of worms and conspiracy theories

To save you some confusion - it won't work.

You can block Service Workers, and hence their cache, using adblocker rules/user scripts. I do so myself using uBlock Origin. Note however that this will break some sites so you need to know how to make exceptions.

Service Workers are a part of the modern web, some sites rely on them to work properly.

Yes, they cache a lot of data locally, most probably unnecessary. Follow the advice already given earlier and clear Storage/Cache regularly if this is a problem.

There are probably some working extensions that deal with them as well. You'll just have to test them.

The Service Worker folder is also safe to delete - as long as the profile is not running. So you could create some kind of batch job to clear these directories regularly if it's a huge problem. I'd stick with just clearing Cache+Storage though.

@ipico You need to go to Computer\HKEY_CLASSES_ROOT\VivaldiHTM.......\shell\open\command , click on right pane on (Standard) and add in string needed parameters before the --single-argument.

Then calling browser from external programs open with the added parameters.

I use this computer every day. Date of change of Service Worker 1.06.2024.
Judging by your words -- the suggestion to disable Service Worker -- the sun has the same idea of its work as the author of the topic.

It's been 6 days now. If I was cleaning the folder, the date would be today. So, in 6 days, it has a volume of 16 MB. And most likely, this volume is constant, i.e. immediately from the moment it is turned on.

I've been through this before. I completely blocked Service Worker, and now I can imagine its meaning and necessity. And that's why I don't recommend doing it.
It is safe to clean, it will still fill up when you turn it on for the first time. No block Service Worker.
You deleted my the keys I posted are harmful and dangerous. What is the basis? Did I created them, or did my neighbor? Maybe you have developed them ? If you so confidently assert their harmfulness. Write a letter to Chromium and say that they have created some kind of stupidity -- Moderator Vivaldi does not approve.
I showed you which keys I have registered for 5 years, no changes. Explain how my computer didn't explode?

Restore my message with the keys -- they will definitely find their user. They don't need you to approve them. They are registered with me on a regular basis. They are created in Chromium. I trust the programmers from Chromium more than I trust you.

The situation is absurd -- I see there is no one here, including you, who knows exactly the purpose of each folder in Chromium. But nevertheless, you take the liberty to delete something that has been working for others for years.

My message was not about the rules of conduct on the Vivaldi forum, but about the work of Chromium. Your authority does not extend to Chromium, it is not in your competence.

sphera

According to the pictures №2 from the first message, it is clear that the author is not satisfied with the size of the 5.4 GB profile cache.
My keys belong to the Service Worker last.
I will say more. My keys, which you deleted, have nothing to do with SW at all. But they have a positive effect on the cache size.

You need to think 2 times before you remember that you are a moderator with a button.
You deleted my keys -- you only made it worse for the author of the topic.

sphera

@Pathduck Then delete all the hundreds of keys developed in Chromium from the message @Zalex108 -- https://forum.vivaldi.net/post/759464

So my keys are taken from this useless collection.

If you have another suggestion, happy to give it whirl.

I wish I did but many/most of the people who have jumped on this thread are very knowledgeable; certainly much more than I am. Consequently, I just ask questions, but maybe one day I'll be able to contribute something useful to forum. In the meantime, I'm sure someone will come up with a practical resolution. I will look forward to reading it, as well. Good luck

I deleted your "keys" - command line switches - and your other irrelevant posts because:

They had nothing to do with the topic subject
They disabled things the user might actually want enabled
They could lead to instability or performance problems

So my keys are taken from this useless collection.

Running the browser with command line arguments are only for those who understand exactly what they do. When you suggest to other users to add these without them understanding properly, they will add them and then come back later saying "Vivaldi is slow, Vivaldi crashes, Vivaldi is bad!"

About the Service Worker folder of 16MB:

It's been 6 days now. If I was cleaning the folder, the date would be today. So, in 6 days, it has a volume of 16 MB. And most likely, this volume is constant, i.e. immediately from the moment it is turned on.

Most likely you don't use sites with SW who cache a lot. Try opening these sites, then come back and tell us what the new size is.
Check also the size of "WebStorage" and see if your caching avoidance switches are working:

https://codesandbox.io/p/sandbox/service-worker-caching-test-hwfl4

Pathduck

@sphera OK, purely for fun and learning let's parse through each of these "keys" of yours:

--disable-gpu-shader-disk-cache

Disables one of several GPU-related caches, used for performance reasons. Users disabling this will see that WebGL/WASM shaders are not cached and have to be recompiled every time they launch their apps, leading to slow start and performance issues.
No relation to Service Workers.

--disk-cache-dir=nul --disk-cache-size=1

Disables web cache only. No relation to Service Workers.
Could lead to performance issues or excessive memory usage as the browser has to rely on memory cache only. In most cases the browser will have to reload every single resource from the website on every request, for users on slow connections this will be a serious performance issue.

--disable-background-networking

From the documentation:
"Disable several subsystems which run network requests in the background. This is for use when doing network performance testing to avoid noise in the measurements."
Has no relation to Service Workers or cache. Is meant only for testing.
Could lead to lack of updates for critical browser components, CRLs, Safe Browsing data and updating extensions in the background.

--disable-features=PreloadMediaEngagementData

Related to media autoplay for preloaded sites. Far as I can tell, this flag no longer exists per Chromium 124 so the switch does nothing.
No relation to Service Workers.

--disable-crashpad

No longer a valid switch. Crashpad-handler process is started and crash dumps written.
No relation to Service Workers.

@Pathduck I have a 475 MB User Data folder. The author of the topic has 5400 MB. Do you see the difference? This has nothing to do with Service Worker.
Raise your eyes higher --- this has to do with the general name of the topic : A shared cache of 31,000 MB is not normal.
475 MB is the correct size. Do you agree?
So, put my post back in place.
My practical evidence would be more useful for the topic than your theoretical "don't turn anything off, leave it as it is."

The author doesn't have any launch keys anyway. The result is in the topic title. He fulfilled your recommendations in absentia, and received 31 GB.

In this topic, every second person has problems with logic - one is looking for deception from the developers of Chromium. Now you have come up with the idea that if you do nothing, then 31 GB will resolve itself. YOU argue for the sake of argument, proving to everyone that 31 GB is the norm.
The norm is the entire browser with a profile and all caches -- 803 MB.
The conclusion is simple and logical: if 475 MB is better than 5400 MB, then return my posts to their place. For this topic, for the Vivaldi forum, my posts turned out to be more useful than yours.

@Pathduck said in 31GB in user data:

We're talking about Service Worker Cache here.

I'm not blind. I can read the title of the topic myself, look at the pictures of the author of the topic. And answer the questions of the topic correctly. In the volume of the profile, Service Worker occupies a small part. Closing my mouth, deleting my posts, limiting the topic only to the SW folder and your guesses and assumptions, you will not help the author of the topic.

Maybe you should turn off the teacher after all? Especially when everyone present here has the purpose of each Chromium folder -- these are guesses and assumptions.

The right way is not to build homemade theories here, slowly digging into documentation for hundreds of keys. Just save important data and check my keys, because at least 1 person has been using them for many years. It's me.
Practice versus theory.
I have a browser startup time of 2 seconds. Is that enough? Record a video? Or should I read your theory and collect all the garbage from all the caches?
I suggest the author not to read anything. Launch the browser with the keys and give us your review of 2 words "Better / Worse".

sphera

@Pathduck I'm amazed at you. The author has your favorite folder SW - 4500 MB, I have it 16 MB. I'm showing you the keys. You delete them.
With results like mine, you should take my keys yourself, circle them in a red frame, and pin them at the beginning of the topic and the entire forum Vivladi.
And let them violate all Chromium documentation.
The result is irrefutable -- 16 MB is better than 4,500 MB. You can't argue with that.

sphera

@Pathduck Great. are you threatening Vivaldi with two sites that he won't pull? Is it scary Spotify? Does it cache a lot ? Ok. I think YouTube caches more than small Spotify.
Video, SW it does not cache anything. Its size is constant. It depends more on the number of open sites. I have shown the startup speed and the operation speed. My keys do not interfere with the work of Vivaldi, as they are designed and recommended by Chromium itself, for those who are interested in them.

Your theories are wrong. These keys are not a secret, they are discussed on many forums. And your attempts to protect Vivaldi users from the results of the Chromium team's work are not appropriate.
Restore my posts.

I use the standalone version, I had some hassle just with the File system folder, which continued seamless to grow disproportionately after each session. It was over 1.5Gb, with the whole Vivaldi folder almost 3Gb. Then I deleted the whole File system folder. Since then Vivaldi no longer increases. Now the whole Vivaldi folder is kept around 1Gb.

@sphera Your posts are still off-topic. You may set up a topic for them if you like.
