Description Chris Dumez 2023-05-10 12:59:38 PDT

When a background WebProcess uses too much CPU in the background, suspend it when process suspension is enabled. We would previously terminate the process which is not as user-friendly and unnecessary when we can suspend to process to stop it from using CPU.
