How to use Performance Mode in eclean

Performance Mode is designed for moments when you want eclean to prioritize responsiveness. It belongs on the Home dashboard because it is a quick control, not a full replacement for reviewing startup apps, services, or Optimizer tweaks.

How to use Performance Mode

1. Open Home: Go to the eclean Home dashboard.
2. Find Performance Mode: Review the current Performance Mode state.
3. Turn it on when needed: Click Enable now before gaming, working, or doing another task where responsiveness matters.
4. Watch for feedback: Read any in-app status message after changing the mode.
5. Turn it off when finished: Click Disable if you no longer need the performance-focused behavior.

The settings icon opens Performance Mode Settings, where you can review Duration, Background Services, Process Priority, and Aggressive Power Mode before enabling the mode from the modal.

When to use it

• Use Performance Mode for temporary sessions where you care more about responsiveness than background convenience.
• Use Booster and Optimizer for more specific changes that you want to review and apply deliberately.
• If you are troubleshooting, change Performance Mode separately from other settings so you can tell what helped.

Technical deep dive

What each Performance Mode setting does

Duration controls how long Performance Mode should stay active. The preset options are 30 minutes, 1 hour, 2 hours, and 4 hours. You can also choose Custom and enter a value in minutes or hours.

The maximum duration is 24 hours. When the timer ends, eclean disables Performance Mode and restores the tracked state for the settings that were active.

Background Services temporarily stops selected non-essential Windows services. In the current desktop app, eclean targets:

DiagTrack
dmwappushservice
WSearch
SysMain
Spooler
WerSvc

These include telemetry, indexing, printing, error reporting, and related background services. eclean records whether each service was running before Performance Mode changed it. When Performance Mode is disabled, eclean tries to start the services that were previously running.

This option does not permanently change the service startup type in the current desktop app. It records the startup type for recovery, but the actual Performance Mode action is to stop running services and restore running state later.

Process Priority watches the foreground app and tries to give it Above normal process priority. eclean checks the foreground process every 2 seconds while the setting is active. When the foreground app changes, eclean restores the previous foreground process priority and boosts the new foreground process instead.

When Performance Mode is disabled, eclean stops the priority worker and tries to restore the last boosted process to its original priority class.

Aggressive Power Mode changes the active Windows power scheme for higher performance. eclean first stores your current power scheme so it can restore it later. It then prefers Atlas Power Scheme if that scheme exists. If it does not, eclean falls back to Windows High performance.

If eclean cannot restore the original scheme later, it falls back to the Windows Balanced power scheme.

How Performance Mode restores state

eclean stores the active Performance Mode state separately from the visible UI settings. The saved state can include:

• the Performance Mode end time,
• service records for services it touched,
• the original power scheme GUID,
• the foreground process priority record.

On app startup, eclean checks whether Performance Mode was still active. If the saved end time is already in the past, eclean treats the mode as expired and restores the tracked state. If the saved end time is still in the future, eclean resumes the active mode and continues tracking it.

What to know before using it

Performance Mode can improve responsiveness during a focused session, but it can also pause background behavior you may expect to keep running. For example, Windows Search indexing, printing, diagnostics, or error reporting may be affected while the mode is active if Background Services is enabled.

If something behaves unexpectedly, disable Performance Mode first before changing unrelated Optimizer or Booster settings. That gives you a cleaner before-and-after comparison.
