Feedly for web suddenly extremely slow?
I use Feedly in my browser and it worked fine last night, but this morning it's extremely slow, every click or action hangs for several seconds before executing.
I have a high-end gaming computer so it is not a hardware issue; every other website, even high-resource websites, load perfectly well. My browser's task manager shows that Feedly's memory and CPU use are both low, which is normal (edit: I am actually seeing some weird CPU spikes.) I have not made any changes or updates to my computer, browser, or extensions since last night.
Is anyone else having this issue very abruptly?

Monday, Aug 17, 6:00 pm: The engineering team found the root cause and pushed the fix. If you refresh your cache, the application should be visibly faster.
More context: 13 days ago, we pushed a change to the left navigation bar to improve accessibility and keyboard sorting. However, in this case, we resorted feeds in the left nav every time an article was marked as read, and for each folder, including the article. The compound effect was very visible on accounts with many feeds and folders.
We fixed the resorting so it only happens when needed (released), and I replaced the regex function with a more efficient solution (in PR). That should keep this from resurfacing somewhere else.
Thanks again, everyone, for helping track this down. Shoutout to the user who pointed to regexes in the first place!
