In the latest wave of anti-ad blocker measures implemented by YouTube, AdBlock users have been reporting widespread performance issues with the extension enabled.

In a thread posted to the YouTube subreddit over the weekend (thanks, 9to5Google) users noted that having AdBlock enabled caused slow load times and increased CPU usage, as one user writes: "This messes up the resources on the computer as a whole. It just kills chrome it seems."

I decided to test this myself, and I noticed that having YouTube open with AdBlock increased my rig's CPU usage by around 17%. While using AdBlock or similar programs is against the website's terms of service, AdBlock is also a massively popular extension. On the Chrome web store it boasts 60 million users.

While you do agree to YouTube's terms of service upon using the site, there's a massive difference between simply blocking AdBlock users and causing increased CPU usage. From what I could see the increase was pretty consistent—so not a dangerous spike—but lower-end laptops mainly used for browsing could start having heat problems. At best it's inconvenient and annoying. It should be noted that this CPU-spiking (if deliberate) isn't something YouTube informs AdBlock users of either.
