Speed That Fits Like a Glove (or… Underwear)

Tommy John has built its reputation on comfort, performance, and products that actually fit the way they should. But as their storefront scaled, with more traffic, richer content, and increasingly complex infrastructure, maintaining a fast shopping experience became more challenging.

And in ecommerce, speed matters. Even small delays in load time can create friction in the customer journey.

Tommy John partnered with Nostra to improve storefront performance using edge delivery infrastructure, reducing latency before content even reaches the browser.

Because when your brand promises no wedgies, your website shouldn’t create friction either.

‍

Tommy John ran a real-world experiment using a traffic split test:

• Control: Existing infrastructure
• Edge (Nostra): Requests served through Nostra’s edge delivery network

Traffic allocation reflected normal production conditions.

Sample size:

• 5.6M sessions — Control
• 20.3M sessions — Edge

This gave statistically meaningful performance comparisons at scale.

‍

‍

TTFB (Time To First Byte) saw the largest improvement at 35% faster.

This makes sense: Nostra operates at the edge layer, meaning it reduces the distance and processing time between a shopper’s request and the first byte returned.

Once that first byte arrives faster, the rest of the page rendering begins instantly, creating downstream improvements in metrics like FCP and LCP.

However, as rendering shifts into the browser, improvements naturally taper since client-side execution is outside infrastructure control.

In other words:

We can make the store load faster.
But we can’t stop someone from opening 37 Chrome tabs while shopping for underwear.

When shoppers land on a page, every millisecond affects:

• perceived performance
• bounce rates
• conversion probability
• checkout completion

A faster TTFB means the page starts loading sooner, improving overall experience.

Or put another way:

Your website should feel like Tommy John underwear, fast, smooth, and no unnecessary friction.

‍

With Nostra’s edge delivery:

• 35% faster server response time
• ~17% faster initial rendering
• Millions of sessions tested in production

The result is a storefront that loads as comfortably as Tommy John feels.

Because when it comes to ecommerce performance:

Slow sites are like bad underwear.
Everyone notices, and nobody likes it.
