Running Ubuntu 18.04
Only extension installed is Full Page Screen Capture, but was not using.
Steps to Reproduce

@jctaillandier do you have rewards enabled. Is your test plan on clean profile?

could you also please go to Hamburger Menu --> More Tools --> Task Manager
Sort by CPU and keep an eye on CPU spikes and which tab/process is causing it.

No Rewards enabled.
Is your test plan on clean profile?
I don't understand the question
Will make sure to open the task manager next time it spikes. At normal it looks like this

OK folks - we've done some investigation and are fairly sure we have found the root cause and the fix 馃槃 Build is happening now and we'll look at releasing a hotfix. Stay tuned 馃槃

@jctaillandier (or others experiencing the issue) if you wanted to try a work-around while we're prepping the hotfix, here's what you can try:
- 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 馃槃

STR that QA can use to verify that https://github.com/brave/brave-core/pull/4999 has been fixed:
- Download & install either https://github.com/brave/brave-browser/releases/tag/v1.5.112 or https://github.com/brave/brave-browser/releases/tag/v1.5.113
- launch https://www.peteresnyder.com/brave/break.html
- Wait ~5-10min while https://www.peteresnyder.com/brave/break.html is opened and you'll notice that Brave will start using a lot of the CPU causing performance issues.

@kjozwiak is that file still needed (i.e. https://www.peteresnyder.com/brave/break.html)? Can you give me a heads up when i can take it down?

@pes10k you can take it down now 馃憤 We're about to release the RC right now so we won't be needing it anymore. Thanks for getting that setup. Really appreciate it.

After updating to 1.5.115, though long term CPU hog seems to be resolved, still seeing a higher CPU usage compared to 1.4.x, especially on script heavy pages.

End user here. Still having high CPU usage issues with Brave Version 1.5.115
Immediately upon opening Brave, I'm getting a Brave Browser Helper process pegged at 100% CPU.
I've also enabled "Enable cosmetic filtering" flag with no effect.

@andrew-pyle can you please open the in-browser task manager? Basically Hamburger menu (top right) => More Tools => Task Manager
I suspect the Bat Ledger process is what is taking all the CPU. Having a screenshot would be extremely useful. You can disable the cosmetic filter - the work-around was just something which would help for 1.5.113 馃槃

@andrew-pyle do you maybe know when this started happening?
NejcZdovc
on 23 Mar 2020
Disabled cosmetic filter鈥擳hanks!
@bsclifton You are correct鈥擴tility: Bat Ledger Service taking all the CPU.
Is there something to be done to correct this on my end?
@NejcZdovc I've been noticing high fan usage for about 2 weeks.
andrew-pyle
on 23 Mar 2020
I have also having this problem. As soon as I open Brave the Bat Ledger Service spikes to 100%. Has been happening for weeks. I cannot use brave like this, I don't have that much CPU to spare.
Notice, an empty browser on Google.com using significant CPU. Note: I have 4 cores, so 24% CPU usage implies it's maxing out a single thread.
I love Brave but I cannot use it right now.

@andrew-pyle would you be maybe able to jump on a quick call to check this one out? If so please send me an email to nejc[@]brave.com. Thank you

I am still getting high CPU usage that is not caused by the BAT Ledge. Any thoughts?
jorda0mega
on 3 Apr 2020
Same as @jorda0mega, but on Windows, not related to BAT, the browser core is taking up CPU usage, might be due to change in adblocker service.
p.s. The CPU spike especially on tab change/cycling.

We do have a crash fix coming - Chromium just released a minor bump (80.0.3987.163). It may not make an impact with performance though (unclear at this time). Thanks for sharing the details @jorda0mega @fhoshino

I am also facing the CPU usage issue on Version 1.8.90 Chromium: 81.0.4044.129 (Official Build) (64-bit)
When I close the browser, laptop does not make any sound.
