40-45% CPU Usage on slickdeals tabs

1,220 429 February 26, 2020 at 11:55 AM
Like the title says. The site is bringing my 9600k to a crawl. Behavior observed on Chrome and the new Edge browser. Noscript prevents CPU usage spiking to this level. What's going on?!

Seeing the same thing. What the hell, Slickdeals? What is this nonsense?

I changed the site settings in chrome to disable javascript for Slickdeals, that made a massive difference. This site is either doing something suspicious or just terrrrrrribly optimized.

Same thing here, on Chrome and new Edge browser, Windows 10. Disabling Javascript also does the trick. Any word on what's going on?

I have same problem here, Chrome and Windows 10. 40+% on any page displaying a moving ad (which seems to cycle through, so can't keep the page open) Not sure if slickdeals or google ads is the real culprit here.

Will try the javascript as mentioned but it will definitely impact my usage of slickdeals if my work PC is choking on Slickdeals ads.

With some trial and error I found out the issue is the runaway announcement bar. The announcement bar is where it currently has the magnifying glass and says "No more hunting for coupon codes! Add Slickdeals to Chrome".

Try deleting that element in Chrome using Inspect and looking in the HTML for <div id="announcementBar"

And you'll notice your CPU utilization instantly drop. Mine went from 90-100% util to 5-10% as soon as I deleted that block.

To make permanent remove the runaway element until Slickdeals can fix it, I'd block it using your favorite ad or page element blocker extension.

I sent this thread into the dev team so that they can look into it.

Thank you for doing some detective work and possibly figuring out the cause, hopefully that will give the devs a good idea of where to start. Smilie

You are correct. The element that is causing the high cpu usage is the moving magnifying glass. Specifically <img class="glass" src="/image-pool/extension/banners/magnifyingGlass.svg" alt="">. When that element is deleted, the cpu goes back to normal.

If you have an adblock extension, you can block just the magnifying glass (right click, "block element") and it should solve the problem, even after reloading the page.

Can confirm that this works. I hope this is fixed soon.

The announcement bar at the top of the page is causing Chrome to use up 30% of my machine's CPU. When I used dev tools to delete that element Chrome went back to its typical usage of ~5% CPU usage.

Just FYI. Rather annoying.

I merged your thread with another thread on the same topic.

This has been ticketed but I'm not sure when it will be fixed.
If you scroll up, someone did provide directions on how to use adblock to remove it.
