Basic information

Steps to Reproduce:

  1. Browse to
  2. Scroll down

Expected Results:
I can scroll (fairly) smoothly

Actual Results:
The browser hangs for several seconds before the page gets rendered, the "slow page" button pops up

More information

I tried this on Linux and didn't give the site a spin on other browser yet. I will and report back in case it's a problem on their side.

Component: Performance → JavaScript: GC

GC activity makes up less that 6% of the total. The page is doing a lot of allocation and some of the minor GCs are longer than we'd like but this doesn't specifically look like a GC problem.

Component: JavaScript: GC → JavaScript Engine

Loaded this in Safari; page load is very similar between Firefox and Safari. I'd argue this is a site issue right now, unless there's something clearly better.

Severity: -- → S3
Priority: -- → P3
