UseEcoQoSForBackgroundProcess removed

Who's implementing?

  • I'm willing to implement this feature myself

The problem

Hi I noticed that the --disable-features=UseEcoQoSForBackgroundProcess flag has been removed in recent updates. This flag was useful for users who wanted to disable EcoQoS for background processes, allowing for more control over performance.

Could you consider bringing it back or providing an alternative way to disable EcoQoS for background processes?

Thanks!

Possible solutions

Restore support for --disable-features=UseEcoQoSForBackgroundProcess.

Provide an alternative flag or setting to disable EcoQoS for background processes.

Add a configuration option in chrome://flags to control EcoQoS behavior.

Research direction
Investigate the Chromium source code to locate where the disable features=UseEcoQoSForBackgroundProcess flag was removed. Check recent commits in the ungoogled chromium repository or upstream Chromium for removal. Consider reverting that commit or adding an alternative flag. Review the current patches and modifications to re implement this flag in the build configuration.
