I am experiencing an untypically high CPU usage since about 10 days.
Windows 10 64bit Intel i9-9900K, 64 GB DDR4 RAM EVGA 2080ti Blck Edition
I am using the Brave - Developer version 1.7.60
I did not install anything new on my PC, but since about 2 weeks the Brave browser consumes about 11% of my CPU power and about 2,400 GB of memory.
It constantly reads/writes on my hard drive with av. 40 MB/sec
What can I do to stop this?
Since posting this the problem magically disappeared.
I’m ok with that
I have noticed this intermittently on Brave Nightly recently. I did a clean install and the high usage resolved, but still uses more CPU than Edge Chromium. Any thoughts from the Brave team?
Agreed. Mine has been around 30-40% cpu usage recently and before it would always site around 4-5%. It’s the main reason I switched to brave. Tried clearing caches, cookies, etc and no luck.
I have the same issue. Running Version 1.5.112 Chromium: 80.0.3987.132 (Official Build) (64-bit) on Ubuntu 19.10, Lenovo y540 laptop. This started happening in the past few days, althought, I’ve been using the browser for a month now. I always have 20+ tabs. Reducing them to 10 tabs did reduce the CPU usage but still not to what is expected.
Currently I have Chrome open with 20+ tabs and Brave with 10 tabs and the pic below shows stats from htop for your ref.
I believe we’ve found the problem on 1.5.113 and are working on a fix
Nightly / Dev / Beta all had an issue too which we solved (involving the Bat Ledger process. That was a different problem)
Here’s something you all can try in the meantime, as a work-around:
- Visit brave://flags/#brave-adblock-cosmetic-filtering
- Enable this option
- You’ll be prompted to restart- go ahead and do that
- Problem should be fixed
Please let us know how this goes! Thanks
Just tried this on linux and so far I’m seeing an improvement on youtube videos. Before this change regular 480p videos on youtube were causing 100% CPU…now its down to 35%.
@Caddark, they closed my topic so i will respond here:
High CPU and Disc usage problem…
How much did you use your pc since the lagging started?
2-3 days until yesterday when i used the PC for more than 3 hours and noticed some kind of problem
Did it lag only when you had the app open?
Yes, i opened Task M and was Brave that was consuming everything
Did you try fixing it? What kind of troubleshooting did you do?
The app was Updated, i tried to “recover to original settings” without sucess (more than 30 min lagging the he*l of my PC)
Do you remember what you were doing when it started?
Nothing really important, watching Youtube videos and using Instagram.
What other applications were open and/or running?
Only Brave, i did some tests and it was 100% Brave “the guilty”
Did you download anything or make any administrative decisions around that time and during the lagging?
Nothing different from usual.
Which windows system do you use?
Did you notice any fluctuations in the lagging during use of the browser and/or other applications?
Youtube videos where the worst part, they were lagging and freezing all the time
What led you to determine the origin of the issue is related to Brave?
If this problem is not usual i will do some tests on my PC, antivirus and this type of thing and try to reinstall it
@Harzeckz May I ask do you have any extensions added to Brave? And have you tried using the built in browser task manager? Try pressing Shift + Escape to bring up the Task Manager for Brave, and take note of any processes that look foreign. (Not the Windows one)
Also, what version of Brave are you on? This can be found at brave://settings/help
I had the same problem on my Macbook and this work-around solved the problem
After further usage of Brave 1.5.113 on my Mac OS Catalina the issue still persists. Here is the task manager
It’s on Youtube and Twitch sites which causes the high CPU usage. This didn’t occur on the previous version
For those users that have been experiencing various CPU/performance issues, could you please download the following version and let us know if things have improved. Once we get enough confirmations from the community, we’ll push this version to our Release channel ASAP so everyone receives the update.
After some hours of use on streaming sites and youtube the cpu usage is way down now with this new version. Thanks
I’ve been having the exact same issue for roughly the same length of time.
The suggested workaround doesn’t help in my case (GNU/Linux - Ubuntu 19.10). Just starting the browser causes fans on my laptop to spin-up after a few seconds. I have one extension (Enpass) but disabling it makes no change. Haven’t tried the linked .114 versions yet.
The issue seems to be fixed now.
Checked the .115 and – unfortunately – no. The problem is NOT resolved. Just running the browser kicks the high cpu and fans in.
Checked Version 1.5.115 Chromium: 80.0.3987.149 (Official Build) (64-bit)
@silverdr if you check the
Task Manager within Brave, do you see the
Utility: Bat Ledger Service process taking a lot of CPU? You can view the
Task Manager via the following:
Hamburger Menu -->
More Tools -->
Could be related to https://github.com/brave/brave-browser/issues/8846 which we’re currently investigating/addressing.
@kamil - yes,
Utility: Bat Ledger Service oscillates around 100 there.
