Browser Pegs CPU at 100%+ for 3 minutes at startup

WHen I start brave on my macbook pro (macOS Version 10.14.6) using , it takes 3 minutes and 15 seconds before the splash screen appears. My CPU and the Brave Browser thread is pegged at 100% or more the entire time.

I’m running Brave version 1.11.97

This happens every time I start the browser. Note that I have all extensions disabled.

Its been this way for a while. Was hopping browser updates and disabling extensions would solve the problem, but no luck so far. Thoughts?

Thanks for reaching out.
Can you try disabling Hardware Acceleration in settings to see if this resolves the issue?

You’ll find this in Settings --> Additional Settings --> System --> Hardware Acceleration

Thanks for the suggestions, but disabling Hardware Acceleration did not help and even slowed it down further. The time to splash screen increased from 3 min 15 secs to 3 min 30 secs.

Also, Note that I do not have a launch problem when I use Chrome.

I also notice slowness and high CPU utilization when visiting some websites, relative to Chrome. For example, is very slow on Brave and I notice the Brave Browser Helper (Renderer) and Brave Browser Process run at 50-70% for over 5 minutes (when I stopped the test).

When I go to the same site in Chrome, the CPU goes up to 30% (for the Chrome renderer) for 10 seconds or so, then drops to 15% and below 10%.

Can you try creating and launching a new browsing profile (Menu --> Create new profile) and see if you get different results?

Hi had same problem yesterday on Windows. Suddenly the CPU came at 100 %. Don’t know if a web site was the source of the problem. I closed all tabs, closed Brave and reopen it. Solved.

Latest beta version on Windows 10.

Wow. That completely changed the response. I created a new profile which sped things up (and didn’t drain the CPU). THen I went back to my old profile and its fast and not consuming the CPU. That seems to have fixed it. Thank you!

That’s pretty strange that your old profile no works properly as well. You didn’t change any settings in your original profile?

No, I didn’t change any settings. The only thing else that changed between my last confirmation of high CPU usage and the dramatic improvement was that I claimed and moved my BAT rewards into my metamask wallet.

One other thing. I think I noticed Brave updated today. Can’t remember when. I am now running Version 1.11.101. Not sure if I was running .101 previously. Is there a way to see when my last version was updated?

FOrtunately, I did include the version in my original email. It was Brave version 1.11.97. I am now running 1.11.101. Maybe the new version is what fixed it.

Clear your cache, then see if original profile is slow.

his old and new profile work fine now
check his post

have a nice day :slight_smile:

I cleared the cache as part of my trouble shooting before I submitted the post. It didn’t make a difference.
