For those users experiencing performance issues due to CPU spikes, could you please capture which service/tab/website are causing the issues using the browsers Task Manager? You can find this information by going to:
Once you have the Task Manager opened, you can sort via CPU column and see which tab/process keeps spiking/causing high CPU usage.
Please provide as much information as possible regarding your CPU usage issue, your OS and Brave version youâre using. You can find your Brave version by:
Method 1: Type in brave://version in the URL Method 2 :Hamburger Menu --> About Brave (or open brave://settings/help in the URL)
The most common tabs that cause problems are Telegram, multicoincharts.com, Slack, GmailâŚbasically whatever is open. Theyâre usually between 80-120% (I dunno how itâs above 100). Right now my CPU is spiking for a tab thatâs not active.
Itâs literally any tab. I can have gmail only open and it will spike like crazy. Then after hours of being online it will randomly go away and then come back a few minutes later. I like your browser but the entire reason I switched from chrome was to avoid wrecking my pc from this high cpu usage. Not to mention how annoying it is listening to the fan trying to cool my computer down constantly. I had 3 tabs open last night and got temperature warnings for my cpu temp at 91-94 degrees numerous times. Going to lose a lot of users if you guys donât figure this out asap.
@LED@presence35 (and anyone else),
To reiterate, its extremely helpful if we can see the actual process, in the browser task manager, that is taking up all the resources.
If anyone reporting can take a screenshot of the process that is spiking in the browser task manager, it would go a long way to helping us narrow down and resolve the issue.
Instructions on how to do this are in the initial post.
1.5.113 Chromium: 80.0.3987.149 (Official Build) (64-bit) running on MacOS Catalina. I have a Macbook pro 2015 - double core 2,7 GHz Intel Core i5.
As always, itâs youtube that takes up all the processing power, although I have seen a more intensive use of the CPU by Brave for some time. I have seen it go up to 110% of the CPU as I posted on reddit (u/katurha)
Another reddit user suggested that itâs the youtube API that spams ads to the Brave Shields, so I tested using only adblock plus and itâs the same. I tried on Safari, and itâs the exact same thing. Without the adblock, both run as usual. So all in all, Iâm guessing itâs not coming from you guys.
Itâs been like 2 weeks like that, and made so worse by the beginning of the fucking quarantine.
I have a decent pc, so I didnât notice the irregularity until I looked in task manager, but whatever the brave process is thatâs abnormally demanding, itâs PID (Iâm assuming âport IDâ?) is 4104.
For me, the real problem is the CPU time thatâs taken up - by Gmail specifically. Messages is bad too but I had no idea until I left Gmail open overnight and checked task manager this morning.
Actually looking at it now, blocking all Device Recognition could have something to do with it, I forgot I set that⌠maybe the service worker keeps trying to do so and getting caught in a loop?
Also, I had to allow all cookies or else gmail would give me a persistent authentication error across the top of the screen.
I do have a decently large amount of emails though if that helps (34,618 to be exact) - but I think theyâre all still less than like 1GB altogether, plus thatâd be more of a RAM issue I think? And gmail doesnât take too much of any types of storage, just the CPU issue.
CPU Pegs basically immediately on launch, will do it even with no tabs open, has for about two-three months. Iâve been using Brave a year or so and know it wasnât doing this most of that time.
If there is anything I can do to reset that somehow or troubleshoot it specifically to help improve things going forward, please let me know. A new profile seemed to have the same issue when I tried it as I noted on other threads.
editing this to add that this seems to correspond to another bunch of reports you can see here, most on macos, though not all, most with no meaningful response, many closed with no response. All noting the same behavior Iâm seeing, almost totally pegged CPU. https://community.brave.com/search?q=bat%20ledger%20service%20cpu
For any users still encountering this issue:
We apologize for the inconvenience and hope it helps to know that we believe weâve found the issue â we should have a new version with the fix out as soon as we can.
In the interim, if you go to: brave://flags/#brave-adblock-cosmetic-filtering , enable this flag and relaunch, you should see CPU usage improve. Please let us know if this is not the case.
Did that but it seems what you refer to may be different from my BAT Ledger problem (not surprising there is more than one issue, theirs seems more sporadic) Any suggestions for what ails mine @Mattches?
Here is a screenshot with the flag you noted enabled. Other details as noted in my previous comment.
@Mattches Iâd certainly agree it is likely something different than the cause of the more spikey but not consistently high CPU usage. But it seems a widespread issue nonetheless based on the link I shared to many other threads describing similar experience, most without significant response. And from the additional person here reporting exactly the same thing shortly after I did.
Iâve had hardware acceleration off from advice in a previous thread or two attempting to get this figured out. On or off it doesnât seem to impact the ledger service. I donât think anyone ever responded with what the next troubleshooting would be after reporting that back. That has tended to be where the suggestions for additional troubleshooting steps stop.
Let me know what else I can do to help yâall get to the bottom of it.
@psm1,
Do you have any extensions installed in the browser at this time? If you were to create a separate profile on your machine, would you also see the BAT Ledger Service spike in the same way?
I only have two extensions installed at all but both are disabled to see if that helped with this. Also both had been installed long before this problem appeared although perhaps some updates to them could have triggered it, that seems unlikely to me though clearly not impossible.
In a separate Brave browser profile the CPU pegging does not occur also that profile has no Rewards turned on and none of the BAT Iâve accumulated browsing which seem like they could be factors. Is there some way to reset/ârebootâ the BAT service that might get it out of its funk in this profile, without losing current data?
If that was directed at me, no. Iâm on macOS Catalina 10.15.2. This is a company machine, it is running Forticlient Endpoint Security nothing around that changed that Iâm aware of between the time this was not occurring and when this became a consistent issue.
