Description

Hello, I noticed that when using with React, JSS causes a lag when removing many nodes. This is screenshot when removing 80 000 nodes.

Versions (please complete the following information):

  • jss: 10.4.0
  • Browser: Chrome
  • OS: macOS

Contributor guide

Research direction
Profile the removal operation to identify the bottleneck. Focus on JSS's internal handling of style removal, particularly the `remove` or `detach` methods. Consider using React Profiler to measure component re renders. Check if the issue persists in the latest version of JSS.
