How to control memory usage in Vivaldi

derDay

I can only talk for me, but it never ever happend, that a single tab could closed by me, because it hang up. Always the whole browser froze so that I have to close and reopen it (not only Vivaldi, also other chrome clones). It's not a pity, because the whole session was re-enabled, but this one-tab-per-process never gave an advantage to me. So happened to me again some days ago.
Fortunately it doesn't occur very often, that a tab is so jealous to me

the integrated taskmanager is more helpful for me.

Other investigation of Vivaldi's memory:
https://github.com/WillyYu/vivaldi_1.9_SoftwareImageDecodeCache
This investigation is a little old, which based on Vivaldi 1.9.
But it should be same as latest version, mainly based on Chromium's architecture.

@derday yes, to me the whole argument about single process being good for crashes is utter rubbish!

it never seems to work with a crash the way Chrome fans say it should
Opera Presto was never crashing anyway, so it's not even an important issue!

@regnas: I'm assuming the tabs automatically hibernate. You should this

Disable this:
vivaldi://flags/#automatic-tab-discarding
Enable this:
vivaldi://flags/#enable-non-validating-reload-on-normal-reload

Hope it works

I'll give it a go, thank you very much...

Disable Hardware Acceleration it is buggy in Chromium based browsers (it cripples lower power PCs, both the browser & PC). I have seen it on over 60 Windows machines where disabling Hardware Acceleration improved performance and lowered RAM usage.

@helmers: I have seen that a lot where the main page is fine but a few of the ads are memory hogs and cause CPU spikes

Deactivating the Update advisor, which remains resident in memory even with closed Vivaldi can also release some memory on PC with limited resources, although then you have to look manually if there is any update available.

@supermecha I cannot find the #enable-non-validating-reload-on-normal-reload flag. Do you know if it's still relevant?
Thanks!

Do ad blockers lessen the size of the page in Vivaldi, or do they do their filtering after the code is loaded?

@paul1149 Adblockers block the sources, that means the page that is actually loaded in the browser becomes smaller, but they use resources themselves. If you really want to block efficiently, you should edit your hosts file on operating system level.

It'd be great if you could explain precisely what "won’t use as many resources" in "They will still be readily available when needed, but won’t use as many resources as your other active tabs." means.

For example, does it mean:

remove everything except the URL, page title, and thumbnail image (and perhaps the HTTP header) [i.e. a glorified bookmark]
move everything to a disk cache, leaving in RAM everything except <see previous>

or other arrangements.

In particular, some of us who have very free RAM or disk (sic) storage, we want things to NOT get cached if we’re not using them.

In my case, currently Vivaldi is using up so much disk storage I'm having to consider buying external storage to migrate files off the system so Vivaldi can cope, and I'm not a walking bank :-(Besides, I'm beyond tired of the amount of time I'm having dedicate to managing disk space.) I'm left wondering if this excess usage of disk is due to Vivaldi caching inactive tabs. Whatever it is it eats up many Gbs of storage even under careful use. My impression is that it uses RAM up to some tipping point, at which it starts eating disk storage in a fairly big way. The only remedy I've found so far has been to quit the browser and start over. I'm hoping the Task Manager will help, but looking at the description I can't tell if it's simply moving things to disk or not.

It’s also be useful to explain what "Background page: Vivaldi" is as opposed to "Browser" in Task Manager are. (In my case these are using 380Mb + 290Mb RAM.)

It might help if developers kept in mind some users will only have, say, 4Gb RAM, with the OS taking 2+ Gb of it. If web pages and/or Vivaldi get greedy with either RAM or disk storage, the system will thrash. (Probably also not good for the SSD card.)

almost 2gb/1,5gb to me >_>

@ozoratsubasa
This seams very high or you have 100 tabs open.

Cheers, mib

All modern browsers (with Javascript compilers) work best with a lot of memory.

!!! NECRO !!!

Why?? Memory is cheap! I even turned off suspending tabs wnen not used, I like them being on, like I left them.

Please give us tips whether to use ram drive for vivaldi cache (which I do now) or just turn off vivaldi cache altogether.

There's nothing relevant here, thank you for taking your time, but it's the truth.
Vivaldi still is the best, although it consumes a lot of RAM, that's not exclusive of Vivaldi. I have 8 GB of RAM and it has never crashed.
The only extension I use is Windscribe VPN and it never brings me any problem.

@chas4: I just did that. We'll see if there's improvement. I don't complain of Vivaldi's performance on my PC, but I always try to make it as smoother as possible.
