How to Fix Chrome Notion Slow and Laggy Issues

Using Notion in Chrome should be smooth and fast, but many users experience frustrating lag and slowness—especially on computers with limited RAM. If you’ve ever stared at a spinning wheel while typing in Notion, or watched pages take forever to load, you know how disruptive this can be to your workflow.

The good news is that there are several proven ways to fix Chrome when Notion runs slowly. Let me walk you through practical solutions, starting with the easiest fixes.

Why Does Notion Run Slow in Chrome?

Before diving into solutions, it helps to understand what’s causing the slowdown. Notion is a complex web application that relies heavily on JavaScript and constant data synchronization. When combined with Chrome’s own processes and other extensions, the browser can become overwhelmed—especially on older or budget computers.

Common causes include:

Too many Chrome extensions running in the background
Accumulated cache and browser data
Outdated Chrome version
Memory pressure from too many open tabs
Notion’s sync processes competing for resources

Now let’s fix these issues.

Quick Fixes to Try First

Update Chrome

Outdated browsers often have performance issues that have already been fixed in newer versions. Here’s how to update:

Step 1: Click the three dots in the top-right corner of Chrome

Step 2: Hover over “Help” and select “About Google Chrome”

Step 3: Chrome will automatically check for updates and install them if available

Step 4: Click “Relaunch” to apply the update

Clear Chrome’s Cache

Cached data can become corrupted or bloated over time, slowing down Chrome significantly.

Step 1: Press Ctrl+Shift+Delete (Windows/Linux) or Cmd+Shift+Delete (Mac)

Step 2: Select “All time” from the time range dropdown

Step 3: Check the boxes for “Cached images and files” and “Cookies and other site data”

Step 4: Click “Clear data”

After clearing the cache, reload Notion and see if performance improves.

Close Unnecessary Tabs

Having too many tabs open simultaneously is one of the biggest causes of browser slowdown. Each tab consumes memory, and when Chrome runs low on available RAM, both Chrome and Notion will lag.

Step 1: Review your open tabs and close ones you don’t need immediately

Step 2: Consider using Chrome’s built-in tab groups to organize and minimize visual clutter

Step 3: For tabs you want to keep open but not actively use, consider using a tab suspension extension

If you frequently work with many tabs, this leads directly to our next solution.

Extension Management

Disable or Remove Unnecessary Extensions

Chrome extensions run in the background on every page, including Notion. Too many extensions can significantly impact performance.

Step 1: Click the puzzle piece icon in Chrome’s toolbar and select “Manage extensions”

Step 2: Review each extension and disable ones you don’t use regularly

Step 3: Remove extensions you no longer need by clicking “Remove” and confirming

Pay special attention to extensions that:

Inject code into web pages
Run constantly in the background
Haven’t been updated by their developers

Use Tab Suspension to Save Memory

If you often keep many tabs open, consider using Tab Suspender Pro. This extension automatically suspends tabs you’re not actively using, freeing up significant memory. Suspended tabs appear as gray placeholders but instantly reload when you click them.

For Notion users who frequently switch between multiple pages or documents, Tab Suspender Pro can dramatically improve performance by ensuring only your active tab uses full resources. It also helps prevent the common scenario where having 20+ tabs open causes Chrome to crawl.

Notion-Specific Optimizations

Disable Unnecessary Notion Features

Notion has features that can slow down the app, especially on slower computers:

Step 1: Open Notion and click the settings icon in the sidebar

Step 2: Go to “Settings & Members” and scroll to “Advanced”

Step 3: Consider disabling “Automatically update page analytics” if enabled

Step 4: If you don’t need real-time collaboration features, you can also try working in offline mode when possible

Use Notion’s Desktop App Instead

While you’re using Chrome, consider that Notion offers a dedicated desktop app that can run more efficiently than the web version. The desktop app is built on the same technology but doesn’t have Chrome’s overhead.

You can download it from notion.so/desktop and sign in with your existing account. The desktop app often performs better, especially for users with slower computers.

System-Level Solutions

Check Available RAM

If your computer consistently runs low on memory, Chrome and Notion will both suffer. Here’s a quick check:

Windows: Open Task Manager (Ctrl+Shift+Escape) and look at memory usage under the Performance tab

Mac: Open Activity Monitor (Cmd+Space, search “Activity Monitor”) and check the Memory tab

If you’re consistently above 80% memory usage, consider:

Closing other applications
Upgrading your RAM if possible
Using lighter-weight alternatives to some of your current apps

Give Chrome More Resources

You can adjust how much memory Chrome is allowed to use:

Step 1: Type chrome://flags in the address bar

Step 2: Search for “Foreground priority”

Step 3: Enable “Foreground priority increase” to give active tabs more CPU priority

Step 4: Restart Chrome for changes to take effect

Note: This is an experimental feature, so use caution.

Network and Sync Issues

Check Your Internet Connection

Notion requires a stable internet connection to sync properly. If your connection is slow or unstable, Notion will feel sluggish.

Step 1: Run a speed test at speedtest.net to check your connection

Step 2: If on WiFi, try moving closer to your router or connecting via Ethernet

Step 3: Temporarily disable VPNs or proxies that might be slowing your connection

Pause Chrome Sync

If Chrome is constantly syncing data in the background, it can impact performance:

Step 1: Click your profile picture in Chrome’s top-right corner

Step 2: Click “Sync is on” to open sync settings

Step 3: Temporarily turn off sync or pause it

Note: Remember to re-enable sync later for data safety.

Creating a Faster Notion Workflow

Beyond fixing the immediate slowdown, consider these habits to maintain better performance:

Work in smaller batches — Instead of having 50 pages open, focus on one project at a time
Use keyboard shortcuts — Navigate Notion faster without loading new pages unnecessarily
Regularly restart Chrome — Closing and reopening Chrome clears memory leaks and refreshes the browser
Keep Chrome updated — New versions often include performance improvements

When Nothing Works

If you’ve tried all these solutions and Notion still runs slowly:

Try a different browser — Firefox or Edge might perform better on your system
Check for malware — Run a full system scan to ensure no malicious software is consuming resources
Consider hardware limitations — Very old computers may simply not handle modern web apps well

Final Thoughts

Chrome running slow with Notion is frustrating, but most issues can be resolved with a combination of browser maintenance, extension management, and smart tab habits. Start with the quick fixes—clearing cache and updating Chrome—then move to more involved solutions if needed.

For long-term improvement, Tab Suspender Pro remains one of the best investments you can make for browser performance. It handles the tab management automatically, letting you keep references open without sacrificing speed.

With these fixes, you should notice a significant improvement in Notion’s responsiveness—especially on computers with limited resources.
