Slow Sites loading
-
@s0hughes Check consumption with internal Vivaldi task manager (hit Shift Esc).
Then you see which process causes so much resource usage.Page loads fast as lightning on my Debian 11.6 KDE is known to be slow desktop environment).
Had you checked if your extensions slow down rendering?
Had you checkt in Vivaldi's Guest window? F2 , type Guest win and hit Return. -
@DoctorG
Thanks for taking a look.
I have zero Extensions. Generally, I don't trust extensions.
Internal Vivaldi task manager: I did.
The 100+% line: I must have screen captured at just the right moment, cause I can watch task manager for minutes and not see that.
Guest windows: yes, in my post I say: example (xfce org) page opens immediately in a guest window.
My desktop is xfce. -

Something in your profile seems to be borked.
Any settings made in internal pagesvivaldi://experiments
orvivaldi://flags
?
Or older/slow GPU driver?
Which display manager? xserver? -

vivaldi://flags
nothing in experiments.
Flags: hmm, I assume anything other than 'Default' is not the default. I have more 'Enabled' or 'Disabled' items than I remember ever setting. This is likely my oldest profile: might have begun using it in 2017, and just recently copied it from older Debian 10 notebook to this Debian 11.
Since there are so many (at least 10+) non-default flags, I was hoping I could filter the list to show only non-default. Seems no way to do that. Is there a human readable file in .config/vivaldi that contains flags?
BTW: since opening this post, I've closed some tabs. Now have 279, and, the example xfce org page now loads immediately. I've not changed any settings. Not even closed the browser. All I did was close about 120 tabs. -

All user-made changes have blue button and are shown at top of the page of vivaldi://flags.

Seems that some background tab goes nuts and ate some resources.
About 300 tabs can be hard work for the browser.
In such case hover current tab in tab bar, open context menu and hibernate background tabs. -
"Hibernate Background": thanks I'll try that next time.
Flags: I'm confused: all my flags show in blue.
I'd reset them, but I'd like to know if I'm reverting any of my changes. In the past I've gone searching for solutions to some pages hiding the v-scroll bar on me. -

I apologise, my answer was not clear for you, the complete button is filled blue when flag was changed, not only the border.

@DoctorG
Flags: Ah, so all my flags are at default values (not to be confused with value of 'Default').
So seems it was a misbehaving tab.I notice in my Task Manager screen capture there was a line item for "tab: How to ... - Apple Support". That is the only tab listed, which I did not open today. That is, it was restored when I launched Vivaldi. I assume all others were restored in hibernated state. Still, task manager shows it consuming 0 cpu, so seems not a great tool for identifying resource hogs, or in this case complete blocking of a page loading, as if the Apple Support page had a lock on some resource needed for the xfce page.
So, I just opened a different profile (having only a couple tabs) and then loaded both the Apple Support page, and then the XFCE page. They both loaded. Then closed xfce, closed the profile, reopen, open again the xfce tab. Still works. IDK.

Still hopeful there is a better way to identify misbehaving tab(s). Same profile. Today: 215 tabs open. I try to visit a search result (in new tab) to serverfault dot com. Result is a new tab showing the correct serverfault URL, but page area is totally white-space. View source shows nothing. I open Window Panel and search for serverfault: no other serverfault tabs. I open cookies, search for and delete serverfault cookies. Still, blank page. Note that while serverfault fails to load, I'm able to open new tabs to other domains, activate and interact with dozens of previously loaded tabs. Just cannot visit serverfault. Then I use Hibernate Background Tabs: the serverfault page then loads immediately. Seems I'm going to get friendly with this Hibernate feature, but wish instead I could identify the problem tabs.
