I have a macbook Early 2015: i5 2.7gh, 16gb 1800mhz, 256gb ssd, El Capitan 10.11.6
I also have istat menus installed. the CPU usage shows around 11%. When I do general browsing at the same time, images loading and scrolling start to lag. This is on the latest Chrome.
When Opera, everything is much much worse!

Any suggestions?
thanks!!

Forgot to mention temp is around 50C.

Safari is even worse.. The entire computer freezes up and you can't do anything for a minute or 2.

I get that issue once in a blue moon on chrome.
 
Weird I'm able to view 4K videos through Safari YouTube utilizing only ~10% CPU. There appears to be something wrong software or possibly hardware wise. Are you able to do other intensive tasks fine, for example play 3D games because if that's the case it appears to be a software issue. Otherwise it might be hardware.
 
I don't think it's only youtube, anything conent heavy like facebook or twitter, I'll get cpu spikes and lag during scrolling. This is with Firefox, Chrome and definitely Opera.


I did a Diagnostic test and report was no issues.

I have far less problems with Safari. On a youtube video, get around 6-9%.

But i don't want to use Safari as I have everything I use integrated into Chrome. I can't just ditch 3rd party browsers...

- That at least suggests a software issue.

If you're confident the issue isn't caused by extensions, add-ons, and plugins in Chrome/Firefox, I would probably do a OS X reinstallation to see what that does.
 
FWIW I watch Youtube videos all the time on my 15 rMBP and there is no stuttering. Here is a couple of things to try

  1. How is your internet connection. Is is fast, with low latency?
  2. See if it is one set of videos that is causing the issues. Maybe one poster screwed up their transcoding or other processing.

I already did Diagnostics and found no hardware issues, that's not enough, in terms of hardware?
 
I had the same problem with YouTube on Chrome on a 2008 mac pro 3.1 running OS 10.11.6
I turned off this setting in Chrome: "Use hardware acceleration when available."
Now YouTube videos run smooth :)
