“The 49MB Web Page” hit #2 on Hacker News today with 314 points and 165 comments, reigniting a debate developers have been avoiding for years: web bloat has reached a breaking point. Pages at the 90th percentile now clock in at 10 MB—four times the median—while some sites load a staggering 21 MB of data, making them harder to render than the video game PUBG. Entry-level phones can’t run “simple” web pages anymore. The web is breaking, but not because of technical limitations. We did this to ourselves by prioritizing developer convenience over users.
By the Numbers: 10 MB Pages Are Now Normal
The statistics should shock us, but they don’t anymore. However, the median web page sits at 2.6 MB, yet the 90th percentile explodes to 10 MB—quadruple the median. Extreme cases like Wix load 21 MB for a single page, while Patreon and Threads each demand 13 MB. Moreover, JavaScript weight alone has increased 28% since 2022. In just 14 years, mobile page weight has ballooned 11.5 times, according to SpeedCurve’s 2025 analysis.
The performance impact is brutal. Additionally, every 100 KB adds roughly 50 milliseconds of load time on a 4G connection. A 5 MB page versus a 2 MB page creates a 1.5-second gap. The industry benchmark sits at 2 seconds, but reality delivers 2.5 seconds on desktop and a painful 8.6 seconds on mobile. As Dan Luu documented, during a rural road trip only lightweight blogs remained readable on slow connections—most commercial sites were completely unusable.
Here’s the kicker: half of Americans don’t have broadband speed, according to Microsoft data. Nevertheless, the real problem runs deeper. Bandwidth has increased exponentially over the years, yet CPU performance for web apps hasn’t kept pace. Fast internet can’t save slow devices. Consequently, the web is becoming inaccessible to people with low-end hardware, even when they have high-end connections.
The Uncomfortable Truth: We Did This to Ourselves
Web bloat isn’t a technical problem—it’s a cultural failure. Furthermore, modern frameworks like React and Next.js prioritize “developer experience” over user experience. Developers routinely ship 2-5 MB bundles by default because tooling makes it easy. Webpack, bundlers, and create-react-app hide bundle sizes until production. By then, it’s too late.
A Hacker News commenter captured the frustration perfectly: “We really shouldn’t allow web developers more than 128kbit of connection speed, anything more and they just make nonsense out of it.” It’s sarcastic, but the underlying point stings. Indeed, we’ve normalized what should be embarrassing. “Everyone’s site is slow” has become an acceptable excuse.
The framework ecosystem enables this by design. Specifically, Next.js apps ship 2-5 MB bundles pre-optimization. Industry data shows these can be reduced 60-80% with proper code splitting and tree shaking, but most teams never do it. Developers feel powerless: “I know it’s bad but my boss wants React.” Meanwhile, the culture celebrates fast builds and hot reload while shipping megabytes to users who didn’t ask for them.
What Bloat Actually Costs: Real Revenue, Real Users
The business impact isn’t theoretical—it’s measured in lost revenue and abandoned users. In fact, sites that optimize to “good” Core Web Vitals thresholds see 15-30% conversion rate improvements. LCP under 2.5 seconds shows 15-25% higher conversion rates than slower alternatives. Poor mobile performance alone wipes out 35% of potential organic visitors.
The SEO math is equally brutal. Position 1 on Google captures 27.6% of organic clicks. Performance determines who wins that spot. Notably, SEO investments deliver an average 748% ROI—$7.48 for every dollar spent—but slow sites get penalized in rankings. Therefore, every 100 KB of unnecessary JavaScript translates directly to lost conversions and worse search placement.
E-commerce sites have the clearest data. Optimizing Core Web Vitals produces 15-30% conversion boosts. Similarly, INP under 200ms delivers 20-30% better engagement metrics. CLS under 0.1 reduces form abandonment by 10-15%. This isn’t about perfectionism. Rather, it’s about money left on the table every single day because culture hasn’t caught up with reality.
The 40 KB Challenge: What You Can Build With Less
The “boring tech” movement proves you don’t need bloated frameworks to build fast, functional sites. In contrast, SQLite, vanilla JavaScript, and plain HTML deliver performance that frameworks can’t match without extensive optimization.
Real companies demonstrate this at scale. For instance, Shopify, GitHub, and Basecamp run massive user bases with monolithic architectures, not microservices. Cloudflare Workers and Expensify are powered by SQLite. Notably, Notion improved page navigation speed by 20% simply by using SQLite for client-side caching. Performance benchmarks show SQLite handling 2,000 queries per second with 5-way joins in a 60 GB database.
The technology works. However, the problem is cultural. Hiring markets expect React experience. Tooling ecosystems are built around bundlers. “Everyone else does it” becomes justification. But the evidence is overwhelming—simple, boring tech scales just fine. We’re just not using it.
Fixing web bloat requires cultural change, not just technical fixes. Accordingly, developers need to measure bundle size in CI/CD pipelines with enforced budgets. Industry recommendations suggest 365 KB of JavaScript plus 365 KB of markup—730 KB total—for a 3-second load on 75th percentile devices. Most sites exceed this by 3-7x.
Choose frameworks by necessity, not by default. Prioritize user experience over developer convenience. Stop accepting “everyone’s slow” as normal. The tools exist to build fast, accessible sites. What’s missing is the will to use them. Half of your users don’t have broadband. Low-end devices are getting locked out of the web. Ultimately, performance isn’t a nice-to-have anymore—it’s a baseline requirement for building sites that actually work for everyone, not just developers with fast MacBooks and gigabit fiber.
