How Page Latency Kills Ecommerce Revenue in 2026 (And How to Fix It)

Fri, 22 May 2026 00:00:00 +0000

Speed is not a feature. It is revenue.

That framing still surprises some CTOs when we use it in a first meeting. Performance has traditionally lived in the engineering team, treated as a quality metric or a technical concern, something you optimise when you have spare sprint capacity. Finance does not talk about it. The board does not ask about it. It does not appear on the P&L.

Except it does. It appears indirectly, in conversion rates, in average order value, in cart abandonment, in paid acquisition efficiency. And the relationship between milliseconds and money is well-documented enough at this point that treating performance as a secondary concern is, plainly, a commercial mistake.

The CDN math that actually matters for e-commerce

Tue, 10 Feb 2026 00:00:00 +0000

When we audit a CDN deployment for an e-commerce client, we don’t start with the dashboard the vendor provides. We start with four numbers. If these four numbers aren’t being tracked, optimized, and reported every month, the deployment is almost certainly underperforming.

1. Cache hit ratio (by content type)

The aggregate cache hit ratio is mostly useless — it’s dominated by static assets that would cache anywhere. What matters is the cache hit ratio broken down by content type:

How CDN node mapping actually works

Mon, 10 Nov 2025 00:00:00 +0000

There’s an interview question that used to be a rite of passage in backend engineering: “Walk me through everything that happens when a user types a URL and hits enter.” Most answers got stuck on DNS and TLS. The part most people glossed over — how the request actually lands on the right CDN node out of thousands distributed globally — is where the interesting engineering lives.

Get the mapping wrong and your users in Singapore are hitting a PoP in Frankfurt. The latency shows up in your P75 TTFB, in your bounce rate, and eventually in your revenue numbers.

Why CDN Vendors Hide Their Prices (And What to Do About It)

Wed, 10 Sep 2025 00:00:00 +0000

You’ve spent hours comparing solutions. One site finally looks right. You want to know what it costs. And instead of a number, you get a button: “Contact Sales.”

If that’s felt like a wall, you’re not alone. But having been on both sides of that conversation — as a buyer evaluating CDN options and as a practitioner who’s helped clients negotiate enterprise contracts — I can tell you the button isn’t evasion. It reflects something real about how these products are built and sold. Understanding the logic makes the process a lot less frustrating.

CDN to Origin Certificates: Your Own CA with OpenSSL

Tue, 15 Jul 2025 00:00:00 +0000

There’s a common assumption that because a CDN handles the TLS connection your users see — the certificate shown in the browser’s address bar — you don’t need to think too hard about certificates on your origin. That’s wrong, and the consequences show up as cryptic error codes rather than obvious failures.

A CDN like Akamai doesn’t act as a transparent tunnel. It terminates the TLS session from the client, inspects and processes the request, then opens a new TLS session toward your origin. Two separate connections, two separate certificate validations.

Is Your Website Ready for the Holiday Rush?

Tue, 03 Dec 2024 00:00:00 +0000

11.11 just happened. Black Friday is right behind it. Then Christmas, then New Year’s. If your platform survived Singles Day with headroom to spare, you might be tempted to relax. Don’t. Each of these events amplifies the same underlying gaps — and the ones that don’t show up under moderate traffic tend to surface spectacularly under peak load.

The preparation conversation usually focuses on infrastructure scaling: more instances, higher database connection limits, load balancer tuning. That’s necessary but not sufficient. Two factors that consistently determine whether a platform has a good or bad holiday season sit outside the application layer entirely: security posture and edge performance.
