Vivaldi becomes very slow and unresponsive when there are multiple sessions (~1000 tabs)
-
I have the latest Vivaldi on windows, i had about 15 sessions
Some of them with 300-150 tabs
Altogether there were about 1000 tabs.
most tabs were hibernated.
It became a very slow and non responsive experience.
I tried to use the windows panel to go over the tabs and close them (based on the tab titles)
The windows panel was useless. very slow and non responsive.
Also some of the time, the windows suddenly switched to another session! it takes over a minute until the browser becomes responsive again...
the only way to go was to delete some sessions... finally the browser became responsive again.
There seems to be a very bad logic programmed into the windows panel.
This panel should be responsive regardless of the number of open tabs.
Also, when I try to select multiple tabs in the windows panel, and they belong to another window, or session, then i get shifted into that session... and if that session is not loaded then it takes long while to load when many tabs are involved... so there has to be a way to make this tool more resilient in many tabs situation so it can be used to help clear out the tabs!Thank you

Hi, do you meant 15 windows with sessions?
Did you check the RAM usage of Vivaldi at this point in the Windows task manager?
Do you have Lazy Loading enabled in Settings > General?
My 16GB are not enough to handle 400 tabs if this is disabled
In my tests with up to 2300 tabs I got no lag at all, laptop specs in my signature, but I use workspaces not windows.
In Settings > Tabs is the Memory saver, it is disabled by default.
May this helps with many tabs.Cheers, mib
