Why is YouTube So Slow?

Disable VPN

Virtual Private Networks route your proxy through different IP addresses. This increases the latency, also known as ping, which may slow down the bandwidth.

So try disabling VPN if you have enabled any. Restart browser and refresh youtube. This might solve it.

Full and Hot CPU

If you run a low spec computer continuously for 8 to 10 hours, it’s CPU temperature can increase. Take note of that and check if the propellers are working. Touch CPU with fingers and if it is very hot, turn it off. Let it cool down and restart later.

Also, check disk size and virus using a good anti-virus program. A low disk can slow down the browser. If your browser is using any extensions like IDM or AntDM, try disabling them. A good practice is to keep only frequently used add-ons. Try clearing the cache and other data if necessary.

High Quality with Poor Internet

Internet connection speed must be minimum 1-2 Mb/s in real-time to play videos of 720p+ higher quality smoothly. If it is lower than that, like 400-500 kb per second, then it will get stuck. Go to speedtest.net and check how fast your internet is.

Note: This above data is not always accurate. Try searching for any big file on the internet and download it. Only the browser can show real-time speed if pressed ‘CTRL + J‘. Mobile users can check the notifications area while downloading a file.

If the connection is giving only 400 to 500 kbps, contact your Internet Service Provider. Meanwhile, you can change the buffering quality in the following ways:

    1. Open a video on youtube.
    2. Click on the gear icon, Settings, at the bottom right corner of the playback screen.
    3. Then select ‘Quality‘.
    4. Then select ‘360p‘ or any lower resolution.

This can make the videos slightly blurry due to a lower amount of pixels. But it can play them smoothly until the connection is fixed.

Block YouTube CDN

Content Delivery Networks (CDNs) are used for caching purposes. The original server will route through a different IP address to display website content. This could slow down or speed up YouTube buffering sometimes. So block YouTube CDN on your own risk.

This is how to disable YT CDN in windows 10:

  1. Search for ‘CMD‘ in the Cortana box.
  2. Right-click on ‘Command Prompt‘ and choose ‘Run As Administrator‘.
  3. Click ‘Yes‘ if the windows smart screen appears.
  4. Then type this code in CMD editor & press ‘Enter’ :
    netsh advfirewall firewall add rule name=”YouTubeTweak” dir=in action=block remoteip=, enable=yes

The above command will block all proxies that route through YouTube CDN. It will then get you content from the original address. Once you enter it, windows will restart the internet connection and the browser, if any opened.

For Apple Mac Users:

  1. Click on the magnifying glass on the upper right corner of the screen.
  2. Type ‘Terminal‘ on the search box and open it.
  3. In the editor, type this command and press Enter: sudo ipfw add reject src-ip in
  4. If prompted, then enter your computer password.
  5. Then enter this command: sudo ipfw add reject src-ip in

Switch To Canadian Server

This is one of the most popular solutions for slow youtube buffering. You can switch the server to Canada in the following ways:

  • Open up YouTube video.
  • Click on its URL.
  • Add ‘&gl=CA‘ in the end without quotes.
  • Press Enter and the video will refresh from the Canadian server.

Final Words:

Some other ways to fix are using an adblocker to disable automatic advertisements that appear in the middle of videos. Other experts suggest that playing on Chrome can be fast. It is so because YouTube uses old Polymer Kit available in Chrome only. Hopefully, Microsoft Edge has implemented the same chromium technology. You can also try to update Flash and increase its cache limit.

But these are optional as the above five solutions will likely fix it. Did this clear your doubts on why is youtube so slow sometimes while playing videos? Either way, if you still want to ask additional questions, feel free to leave them in the comments below.
