Chrome runs so many processes because it's designed to isolate different parts of the browser for better performance, stability, and security. Each tab, extension, and even some website features can run in their own separate process. This helps prevent one problematic site or plugin from crashing the whole browser.

1. Each Tab Gets Its Own Process

When you open multiple tabs in Chrome, each one typically runs as a separate process. That means if one website crashes or freezes, it doesn't bring down all your tabs. It also allows Chrome to manage resources more efficiently — like giving more CPU or memory to a video-heavy tab while throttling background ones.

• If you open 10 tabs, you might see 10 processes in Task Manager.
• Heavy sites (like YouTube or Facebook) often use more resources than simple pages.

This design choice makes Chrome more stable but can look overwhelming if you're not used to seeing so many entries under "chrome.exe" or "Google Chrome" in your system monitor.

2. Extensions Add Their Own Processes

Every extension you install in Chrome usually runs in its own process too. Some extensions are lightweight, but others — especially ad blockers, password managers, or script runners — can be quite resource-intensive.

• Go to chrome://extensions/ to see what you've installed.
• Disable or remove unused extensions to reduce process count.

For example, if you have uBlock Origin, LastPass, and Grammarly all active, they could each be running in separate processes, adding up quickly even with just a few tabs open.

3. Background Services and Renderer Processes

Beyond tabs and extensions, Chrome also runs several background processes:

• Browser process : Handles the UI, address bar, bookmarks, etc.
• GPU process : Manages graphics rendering (like animations or video).
• Network process : Handles all the data being sent and received.
• Renderer processes : These are the main ones you see — they actually display web pages.

So even if you only have a couple tabs open, you'll still see several processes running behind the scenes just to keep everything working smoothly.

4. Why It Might Be Worse on Your Machine

Sometimes, Chrome ends up using way more processes than usual. Here are a few common reasons:

• Too many tabs open at once
• Multiple heavy extensions running
• A site that uses lots of background scripts (like dashboards or web apps)
• Chrome bugs or outdated versions

You can check which processes are using the most memory or CPU by opening Chrome's built-in Task Manager ( Shift Esc ) and sorting by memory or CPU usage.

If you're worried about high resource usage, try limiting open tabs or auditing your extensions. But in general, having many processes is normal for Chrome — it's part of how it stays responsive and stable.基本上就這些。
