Degraded performance in CP Assets view for folders with many subfolders #5809

The performance of the assets page in the CP when it is asked to open a folder with a lot of subfolders in it is resulting page crashes in Chrome, Firefox and Safari on a recent MacBook Pro. Estimate is about 15k sub folders in the Assets volume that can be seen in the screenshots below.

If the folder has never been opened in the particular browser of choice the page will load ok, but as soon as the attempt to expand the folder is made, this will result in the freeze. Subsequent page loads will then also freeze, as the browser appears to attempt to remember the user preference and have that folder opened, making the assets page essentially unusable 😫.


Steps to reproduce

  1. Have a lot of sub folders in a volume or folder
  2. Attempt to expand the folder to show its contents

Also affects modal asset windows triggered from asset fields, making them also unusable.

This is a known issue. We’re considering a couple ways to solve it, such as #1629. I’ll leave this open and update it once we have a solution.
