2015 13' rMBP sluggish, Facebook unusable on any browser

[audiosmurf]

I've had the 13 inch 2.9ghz rMBP from early 2015 for a while, it's become quite slow to the point where Facebook is just unusable on any browser. Cycle count is only around 120, anything I can do to speed this up a bit? Also gets very warm frequently.
Thanks.

Is it other a sites or just facebook. If it is only facebook, take a look for video or other animations playing.

Slowish on other sites too but Facebook is by far the worst. Scrolling down is a lagfest. Turned off autoplay for videos with no change.

What does the Activity Monitor show? Especially the CPU column.

There's a screenshot of the top of the Activity Monitor.

Do you have adblock or anything installed? A friend of mine had bought a early 2011 15' and safari was almost unusable, although the computer felt very fast overall, couldn't even play flash games, installed adblock and the computer was zipping around safari as fast as my maxed 15' 2015

Yep, have adblock installed! I think it's struggling with constantly loading more content...

Mhhm, strange since activity monitor doesn't show the CPU being hogged, you said it gets warm a lot is it possible its dusty and causing CPU throttling? we have a 3.1 13' 2015 as well and it runs everything great.

I wonder if this is related:

My issue was with Safari, but it started getting worse quickly whenever I tried using Facebook. I haven't looked to see if Chrome would have a similar problem.

Hi there, this seems very possible! What's the best way to clean it out?

I'd take off the bottom of the computer (fairly easy although nothing is user-upgradable) and use some compressed air to spray out the computer, be sure to make sure not to shake it of course or liquid may come out. It'd be pretty obvious if this were the cause as there would be a good amount of dust when you removed the cover, so you might want to check before spending the cash on the compressed air.

OP:

Temporarily disable Spotify and don't use Chrome.

Run this way for 2 days, if you can.

Does anything change?
