Brave is painfully slow: macOS 15.0

Brave takes a lot of time to load websites
How can this issue be reproduced?

  1. Install brave on latest macOS stable version
  2. try to load anything

Expected result:
The websites should load much faster
Brave Version( check About Brave):
1.70.117
Additional Information:
Everything worked perfectly fine but I reseted my computer. After install, I think I had no issues for maybe 2 days and now it began to be slow.
The only extension installed is Bitwarden. I touched very very few settings.
I have a VPN but it works well and fast for other apps and on Android and turning it off changes nothing.
I have Lockdown mode enabled but turning it off changes nothing
The very strange thing seems to be that Safari doesn’t work that fast either, as you can see in my screen recording of Mullvad Browser (works as expected) Safari and Brave and Activity Monitor : https://send.tresorit.com/a#PFFEx6hmIHDG0E-8HjUztw

I just created a new Brave Profile and it works perfectly ! What should I do ?

Well I found the source of the issue.
Setting “Blocking trackers and advertising” to “Standard” immediately speeds up the browser af.
I suppose this is not normal and you should investigate this issue.

Now I rebooted the computer and even with this setting set to “standard”, it’s as painfully slow as before. Even if I create brand new profiles

discuss.grapheneos.org loads instantly but not edition.cnn.com or discuss.privacyguides.net are slow. So there is something in those more complex websites that slows them

Have MacOS 15 here, using a VPN may affect loading speeds. would test without it (or test with it enabled but on a closer destination country)

Thanks but the same behavior happen without Windscribe VPN

Needs more debuging tbh. Try clearing cookies/cache, test in private window mode. Nothing in the OS should be it any slower

Hi.
Clearing cookies doesn’t help. How do I clear cache ?
Here you can see a page taking a lot of time to load. https://send.tresorit.com/a#-dKxQMEMCfRefIz7jO0HkA
Brave Search works instantly. I disconnected from the VPN before the screenshot. My wifi is very fast, I am at home.

And btw the same behavior happen if I try in a brand new profile

can you test in Brave Beta?

Just installed it. It works perfectly in Beta
What should I do then ?
I would really like to continue to use Brave Browser, if possible in stable version.
Since it already happend to me once and now again, I am sure it happend to other people too and there is something that needs to be fixed

could be profile related? could try a reset, brave://settings/reset

No sorry I rested settings and it is still slow, even without VPN
And I always try to modify as few as possible the settings of apps and os

the same behavior began to happen with Brave Beta. Please help

Seems there is no support team at Brave ? Should I just switch to Safari to be able to browse the internet again ?

Damn
I even restted my whole mac to solve this problem.
Before reseting, my set up was 1 admin profile and two standard profiles and Lockdown mode. I reseted with the same setup. In the standard profile, it began to be really slow again so I resetted again without lockdown mode and only 2 admin profiles.
it worked really well in the first profile and then when I switched in the second profile, it began to mess up (really slow again).
I think it is related to my multi-profile set up

i reseted the computer and setup ONE admin profile and ONLY installed brave and it is a anormally slow again!
