JavaScript execution too slow
-
Hi All.
Noticed lately, that vivaldi got very slow on javascript execution and it eats up a whole 1 core computation power to perform simple tasks, which usually work flawlessly like clicking on a youtube-video-thumbnail to go to the video.
or applying sort or filter to the elements of some list of items with pictures. and so on.anybody knows how to get over it?
Vivaldi 1.13.1008.36 (Stable channel) (64-bit)

@gwen-dragon ok. it happened before on pages like vk.com when you do a video search.
it happens now on Google calendar, Google inbox, there it is not only slow, but after some time, some features stop to work at all. like opening an email to read, or creating an event and edit it in a popup.when you also try to read i.e.. a manual to ROOT framework, let's say, Google for root TH2F, the page has lots of mathjax fields. and while other browsers are processing it in a background, so you can scroll the page normally at load time, vivaldi hangs for many seconds before you can do anything.
I use Linux, AMD - A8 processor, memory, will write later,, but it is a DDR3, 2000+ GHz

@Gwen-Dragon See the screen shot:
-
@gwen-dragon I see
the 1.14 is marked as ~Unstable in the gentoo repository
that's why it hasn't updated
I will allow my portage to update to ~Unstable version and then test around. -
@gwen-dragon The output of vivaldi://gpu looks much better now (if Hardware accelerated means better), but the problem persists.
the rendering of https://root.cern.ch/doc/master/classTFile.html is still as slow as it was before.
and other services i mentioned are working as bad as before.i will try an update then.
and see what happens -
funny thing is.
when I set ignore-gpu-blacklist enabled
even so simple page as vivaldi://gpu has rendering artifacts, those are not critical though.
after an update to 1.14
with ignore-gpu-blacklist DISABLED- searching for a video on https://vk.com/video results in 8s lag
- openning https://root.cern.ch/doc/master/classTFile.html results in 14s lag
- THIS page lags 0.5-1.5s on scroll
with ignore-gpu-blacklist ENABLED - https://vk.com/video works exactly the same way
- openning https://root.cern.ch/doc/master/classTFile.html results in 11s lag
- THIS page gets noticeably lesser lags at max duration 0.5s
all values are measured multiple times (3 times) with closing and openning the browser after every test

@gwen-dragon I have no problems with video decoding
I only have problems with the search result rendering
-
i mean this area takes 8 seconds to render
-
this is rediculus.
but it was the AdBlock which I didn't install manually. it was there by itselfas i disabled AdBlock. everything got fast again.
have to look then for a replacement. maybe another adblocker will fine.
this one i will uninstall. -
I switched to AdBlock Plus. and everything works at lighting speed.
this is insane. I could not expect the adblocker to block the whole page rendering.
to break javascript-scripts (i got error messages on multiple pages like "lightframe.js error") and in addition to not block ANY add at all AND to be preinstalled by default. -
@gwen-dragon thanks for guiding me.
i have to say I realy didn't expect AdBlocker, which is used by million of users to be the issue. -
@visor1933 said in JavaScript execution too slow:
AND to be preinstalled by default.
Small correction - with Vivaldi NO extensions are installed by default! Maybe you installed it a while ago and forgot about it.
