Chrome"s multi-process architecture means every tab, extension, and subframe gets its own slice of RAM. This provides stability (sandbox) but incurs massive overhead. Use the internal Task Manager to audit your footprint.

The Manual Fix

Audit Processes: Press Shift + Esc. Look for processes labeled Subframe or Utility. These are often ads or background workers.

Kill GPU Process: If the GPU Process is over 1GB, click End Process. Chrome will restart the graphics driver automatically, often reclaiming 500MB+.

Remove Heavy Extensions: Sort by memory and remove any extension using >100MB consistently.

Remove Heavy Extensions: Sort by memory and remove any extension using >100MB consistently.

The Automated Fix

SuperchargeBrowser is designed to be lightweight (<20MB). It replaces heavier extensions (like ad blockers that use 300MB+) and automatically kills the heavy Subframe processes inside background tabs by suspending them.

The Hidden Cost of "Utility" Processes

When you look at Chrome Task Manager, you will see many processes that aren"t tabs. Network Service, GPU Process, and Utility: Audio Service. These grow over time as you browse. The only way to reset them is to restart the browser, which breaks your flow.

The "Subframe" Problem

Modern ads load in iframes (Subframes). Each one can spawn a new Chrome process. A single news article might spawn 10+ subframes, eating 300MB of RAM just for ads.

How We Fix It

Ad Blocking: By blocking the network request for the ad, we prevent the Subframe process from ever launching.

Suspension: When we suspend a tab, we kill all its child processes. That news article goes from 10 processes (1GB) to 0 processes (0GB).
