High CPU and RAM Usage

@SomethingRandom,
Please try all suggested solutions mentioned above and confirm that they do not change the behavior:

In addition, please try creating a fresh browser profile and browsing normally for a while and see if the issue persists when using the new profile (ensure you close the original profile window during this test as well).

Checking back in – can anyone who is still encountering this issue and tried all previously suggested solutions in this thread tell me if you have Rewards enabled and if so, is it both Rewards and Ads?

I have both enabled. I noticed that sometimes when this issue happens it seems that service workers from certain sites hang around. I tested a few in Edge at the same time in edge those service workers initiated but went away once the tabs were fully loaded (or video loads in) in Brave those service workers don’t stop and keep taking up the RAM.

I restarted the computer a few minutes ago and now Brave seems to be performing much better than usual (even better ever).

Unrelated question: is there a way to pin a tab so that it’s perpendicularly pinned in any window I open?

Update: just happened again but in general when the spikes aren’t happening Brave seems to be performing much better.

Seems like it is definitely something to do with service workers I noticed that last time a spike happened I noticed that a spike happened specifically with the RAM usage of the YouTube PWA once I closed it took a while for the service worker to go away after it went away RAM usage dropped to normal. When I first opened the YouTube video in a regular browser when I opened it into the PWA the service worker stayed until after I closed it? Are these different behaviours normal?

Just experienced a spike for the first time in a few days. 2 things are different this time 1 Windows Task Manager shows the main Brave process using exorbitant amounts of RAM (and this time CPU also) and there’s a second process in Task Manager that’s also using a tom of resources and the second thing that’s different is that is it spiked and than has been fluctuating at unusually high numbers for about 10 minutes. Since this occurrence started readings from Brave’s Task Manager reduced a couple of minutes in to the spike.

It ended while I was writing this post.

Here’s a link to a screencap I took while the extended one was happening: https://youtu.be/E7raQjXoMKo

The video is still processing but it should be up soon.

You are running quite a few extensions here, does private window mode, no extensions installed improve performance? @SamGreenwood

Yes but this behaviour is new and I’ve been using the extensions I’m using for ages. As seen in all the screenshots I posted show the util values of the extensions max out at around 230MB. Also there are other people saying that they are experiencing similar issues so that indicates that unlikely to be something specific to my system (just to be clear, I’ve actually had this issue on multiple systems). Obviously running with no extensions would improve the baseline performance but if I remember correctly the spikes were still happening.

Hi,

Extensions changes over time, performance can vary from each version update. Because you use extensions X, Y, Z. Doesn’t necessarily mean they’ll also act or behave the same way forever.

We’re investigating performance issues;

I deactivated Grammarly for a few minutes and Brave actually dropped considerably in RAM usage between when it wasn’t active and when it was. I’m not saying that it helps (that wouldn’t make sense) but that would seem to indicate that it’s something else.

@Markook @Delka @SomethingRandom @nununu @Pete3 @ikwtif @tchambers @Theo90 are any of you still having this issue?

No, it stopped happening for me.

Grammerly extension is notorious for hogging cpu/ram resources (see previous link)

Fans running high as we speak. I only have UBlock and Honey installed.

Also Honey will impact resources.

I haven’t had that issue from my side. Obviously, the initial feeling that BRAVE is ‘lighter’ than the competition is no longer valid argument for me.
I have formatted my computer yesterday. But, even after a fresh installation, and 7 tabs, I see that status below.

Brave (like Chrome is multi-threaded). Each extension will have a cpu thread (and maybe more depending on the extension), as will Brave itself will have some processes for itself.

Looking at the screenshot, it’s not too bad, most of the processes are low memory. For a more detailed look of processes look at the Brave settings/Task manager.

Just to clarify when I mentioned multiple processes I wasn’t referring to threads there was a second full process using over a GB. Some of us are definitely having issues I agree with you on thr last poster though.

@tchambers @Pete3 what platform are you using?

I am on Windows 10 20H2 OS Build 19042.685
