📊 Field data tells you what’s slow. Lab data tells you why. Varun Raman, Customer Support & Content Lead, @gtmetrix explains each data type and how to use both to optimize website performance.

We analyzed a page with 22.5MB uncompressed size. 17MB of that? JavaScript. 140 JS requests. 19.1s JS execution time. 4.6s TBT 🧐 Too much JavaScript hurts performance and your visitors feel it. Learn how you can fix it: gtmetrix.com/blog/slow-webs… #webperformance #gtmetrix

65% of CMS sites use WordPress. Yet, over half fail Web Vitals 🧐 Good performance is essential if you want more users and more revenue. Together, GTmetrix and WP Rocket make it quick and easy to optimize performance: gtmetrix.com/blog/wordpress… #webperformance #gtmetrix #wprocket

We found a page serving 76MB of images🤯 In the Waterfall, 4 heavy images stood out, the top one over 25MB! There’s no excuse for images that heavy; you'll hurt performance and your visitors' wallets. Optimized images = happier visitors. Learn more: gtmetrix.com/blog/a-designe…

@typewriter2911 @CyberEssentials Hi Justin. MFA is coming soon. Please reach out through our contact form (gtmetrix.com/contact.html) so that we can give you more details.

@gtmetrix why do you have zero MFA options? We are going to have to close our account with you due to this as it is not compliant with the latest version of @CyberEssentials Plus accreditation.

📢 GTmetrix Update: Our maintenance has been completed and things are back to normal. Feel free to reach out to our support team if you do encounter any issues. Thanks for your patience and support!

📢GTmetrix Maintenance Update: We're back up - but currently experiencing degraded performance. Our team is currently investigating and working on a fix.

@dewolfe001 Apologies for the delay. We are finishing a migration and investigating slow queue speeds now.

What's up with the pro accounts at @gtmetrix ? I'm on a queue that's spiralling upwards?

📢 GTmetrix will be temporarily down for planned maintenance at 12 PM PST. We'll notify you once we're up and running again - Thanks for your understanding!

Slow sites hurt UX, conversions, and SEO. GTmetrix breaks down your site’s performance with Lighthouse insights. In our latest post, we provide a GTmetrix overview and compare it to 6 major alternatives: gtmetrix.com/blog/gtmetrix-… #webperformance #gtmetrix #lighthouse

📢 GTmetrix Lighthouse/Chrome version Update: We've upgraded GTmetrix to Lighthouse v12.6.1 / Chrome v142 now. Note that our default User-Agent string has also changed in line with this update.

@gamesover We actually use a real Chrome browser 😁

If your homepage causes the virtual browser on @gtmetrix to run out of memory when running a performance test, you're doing something wrong. For the record, I've never seen this happen before. #notMyCode
