Top 5 JAMstack Website Speed Statistics for 2022

Nothing can affect your user experience (and SEO) more than website speed. In our hunt for faster and smarter website development frameworks, we came across JAMstack.

Now, some devs swear by the JAMstack jam. (Spoiler alert: we’re one of them.) But let’s be objective and answer the question once and for all: how fast is JAMstack?

Top 5 JAMstack Website Speed Statistics for 2022

#1 - JAMstack Websites Have Faster Server Response Time

Our go-to resource for all things UX is the Chrome user experience report. And when it comes to speed, JAMstack easily outruns monolithic CMSes.

When looking at the Time To First Byte (TTFB), 37.7% of JAMstack websites load faster than average. Remember that TTFB is a crucial metric because it defines the website server response time.

Older, slower websites take longer to load, affecting your conversion rate significantly. After all, website conversion rates drop by 4.42% for each additional second of load time.

Check out the difference between the number of slow JAMstack and traditional CMS websites, too!

Over 39% of traditional CMS websites load too slow (compared to only 11.98% of JAMstack websites).

#2 - JAMstack Renders FCP 2x Faster than Traditional CMS

Next up: it’s on to content, AKA our bread and butter. If your visitors see the endless loading circle, they will bounce. You want to ensure your website provides feedback to users in the form of the first contentful paint (FCP).

Chrome’s UX report again shows us that JAMstack websites outperform traditional CMS:

JAMstack loads those first bits of content faster, while WordPress websites still scramble to collect all their moving pieces.

One reason why JAMstack websites are so fast is that they’re pre-rendered. Your JAMstack website uses the static site generator. Then, it adds functionality through APIs and JavaScript.

Your visitors don’t have to wait for everything to load before seeing the content they came to your website for. By default, the JAMstack architecture sets you up for better FCP results.

#3 - JAMstack Websites Respond to Interactions Faster

Have you ever spent a few seconds trying to click a website button, only for the page to pretend like you weren’t even there? If you’re anything like the average internet user, the experience is so familiar that you might want to hurl rocks at the moon.

We call the time it takes your website to respond to interactions first input delay (FID).

And when comparing traditional CMS performance to JAMstack websites, there’s no doubt that JAMstack gives visitors what they want faster.

Visitors won’t hate you if your website doesn’t respond to their interactions lightning-fast, but they will bounce.

Your website will come across as non-functional. They’ll return to the source to find a competitor whose site runs faster.

Fortunately, over 92% of JAMstack websites receive “Fast” FID scores.

#4 CDN Makes JAMstack Websites Load 2x Faster

JAMstack websites typically use Content Delivery Networks (CDN) to display content faster.

Firstly, they use location-based servers, so your New Yorkers get content from the US server, while your Irish visitors get information straight from the Ireland server.

They also cache the content, so it's not recreated whenever someone accesses your website.

(Distance does matter.)

On average, websites that use CDN load 2x faster than other websites.

Similarly to how JAMstack websites serve pre-built markup to your visitors, CDN serves static content to users faster.

This doesn’t take away from the website’s performance, but it gives users the results they need before you can say: “WordPress is so 2001!"

Regarding SEO, JAMstack websites' CDN usage means that Google can increase your crawl budget. Traditional websites are prone to server errors when Google requests too many crawls. JAMstack websites can handle the traffic, so your servers won’t get overloaded, and Googlebot can crawl your pages to its heart’s liking!

#5 - Building a JAMstack Website Is Faster

Now that we’ve proven that JAMstack beats traditional websites regarding speed, let’s talk talent. The better your devs are, the better your site’s performance will be.

And with the number of JAMstack developers constantly growing, you’ll be in good hands.

Developers love JAMstack because it’s framework-agnostic. They don’t need a course in a different programming language to develop JAMstack websites. Instead, they can focus on the functionality you need.

Here at Mawla, all our projects start at 70% complete.

The JAMstack foundations allow us to focus on tailoring the website to your unique requirements with additional features, API connections, and fine-tuning the performance.

Wait... Why Is JAMstack so Fast?

Firstly, JAMstack serves pre-built markup via a Content Delivery Network to your visitors. In non-tech speak, this means it keeps a portion of your website pre-heated for visitors.

Once they land on your website, they’ll get their meal extra fast.

Secondly, JAMstack websites are decoupled from your server. Traditional websites must load in full before displaying the first bit of content to your visitors. Yes, this means third-party API integrations, database information, and more.

JAMstack got rid of that luggage a long time ago.

Thirdly, if your developers are drowning under the weight of APIs, JAMstack alleviates the pain. A traditional monolithic website can only handle so many APIs and integrations before it gives up. JAMstack is an extrovert; it wants to connect.

Finally, JAMstack is a growing framework. With more devs choosing to use it every year and more open-source communities, JAMstack is being created as we speak. Every expert can contribute with their knowledge, shaping the framework that will power the websites of the future.

Yes, JAMstack websites are fast, but that’s just the tip of the iceberg. If you dive deeper, you’ll find an ocean full of performance, SEO, and UX benefits.
