The improvements made the CDN efficient enough to roll it out across all web hosting plans, including Premium and Single, at no additional cost.<\/strong><\/p><p class=\"wp-block-paragraph\">&ldquo;By making our CDN more efficient under the hood, we can now give every customer a faster, more resilient site without asking them to pay for more infrastructure costs. That&rsquo;s the kind of improvement that should be standard,&rdquo; said Saulius Lazaravi&#269;ius, Chief Product Officer at Hostinger.<\/p><p class=\"wp-block-paragraph\">After completing the CDN optimization, Hostinger automatically migrated existing web hosting customers who met three conditions: they used Hostinger DNS, weren&rsquo;t already running another CDN, and hadn&rsquo;t opted out of the rollout. New web hosting customers now have the Hostinger CDN enabled by default.<\/p><p class=\"wp-block-paragraph\">Following the rollout, early infrastructure-wide data show that average response times fell by 26%, from 965 ms to 714 ms. The performance gains were most prominent on SSD-based web hosting servers, where average response times improved by 35%.<\/p><p class=\"wp-block-paragraph\">SSD servers had less performance headroom than newer NVMe-based infrastructure, so reducing backend load led to a larger improvement in response times. Although they now make up only a minority of Hostinger&rsquo;s fleet, SSD-based servers saw the biggest gains from the optimization.<\/p><div class=\"wp-block-image\">\n<figure data-wp-context='{\"imageId\":\"6ad010bf72559\"}' data-wp-interactive=\"core\/image\" data-wp-key=\"6ad010bf72559\" class=\"aligncenter size-large wp-lightbox-container\"><img decoding=\"async\" width=\"1946\" height=\"948\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/4\/2026\/10\/cdn-response-time-data.png\/w=1024,h=1024,fit=scale-down\" alt=\"Server response time improvement. \" class=\"wp-image-10582\" srcset=\"https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/4\/2026\/10\/cdn-response-time-data.png\/w=1946,fit=scale-down 1946w, https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/4\/2026\/10\/cdn-response-time-data.png\/w=300,fit=scale-down 300w, https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/4\/2026\/10\/cdn-response-time-data.png\/w=768,fit=scale-down 768w, https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/4\/2026\/10\/cdn-response-time-data.png\/w=1536,fit=scale-down 1536w, https:\/\/imagedelivery.net\/LqiWLm-3MGbYHtFuUbcBtA\/wp-content\/uploads\/sites\/4\/2026\/10\/cdn-response-time-data.png\/w=1024,fit=scale-down 1024w\" sizes=\"(max-width: 1946px) 100vw, 1946px\" \/><button class=\"lightbox-trigger\" type=\"button\" aria-haspopup=\"dialog\" data-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\" data-wp-init=\"callbacks.initTriggerButton\" data-wp-on--click=\"actions.showLightbox\" data-wp-style--right=\"state.thisImage.buttonRight\" data-wp-style--top=\"state.thisImage.buttonTop\">\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewbox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\"><\/path>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n<\/div><p class=\"wp-block-paragraph\">The improvement was driven in part by less pressure on the lower-tier web hosting servers. These servers used to operate at 20&ndash;30% above the average load of Hostinger&rsquo;s Business and Cloud infrastructure. Following the rollout, the trend reversed, with Premium and Single web hosting servers running at 15&ndash;20% below that average.<\/p><p class=\"wp-block-paragraph\">The benefits extended beyond websites that use the Hostinger CDN. By reducing overall server pressure, even websites without the CDN enabled achieved faster response times.<\/p><p class=\"wp-block-paragraph\">Rather than adding new servers or hardware, the company <strong>reduced the computing resources needed to run its CDN by 45&ndash;50%<\/strong>.<\/p><p class=\"wp-block-paragraph\">A key part of that effort was making encrypted connections more efficient. Hostinger migrated SSL certificates from RSA to ECDSA, reducing CPU consumption for SSL-related operations to roughly one-third of its previous level.<\/p><p class=\"wp-block-paragraph\">The company also adopted kernel Transport Layer Security (kTLS) and improved session resumption, further reducing the resources needed to serve returning visitors.<\/p><p class=\"wp-block-paragraph\">Another major gain came from Hostinger&rsquo;s in-house traffic engine. Instead of multiple regions independently fetching and processing the same content, requests can be routed through the edge closest to the website&rsquo;s origin using warm, pooled connections.<\/p><p class=\"wp-block-paragraph\">This cut connection setup times from tens of milliseconds to around 3 ms and reduced global CPU usage by approximately 20%. Processing tasks, such as image optimization, can also be reused across the network rather than repeated in multiple locations.<\/p><p class=\"wp-block-paragraph\">Other smaller engineering improvements contributed to the remaining gains, including eliminating internal lock contention, moving bot fingerprinting into native code, and streamlining storage, logging, request handling, and edge process recovery.<\/p><p class=\"wp-block-paragraph\">These optimizations made it possible to offer the CDN across all of Hostinger&rsquo;s web hosting plans rather than reserving it for higher-priced plans as before. The CDN rollout is now <strong>completed across all of Hostinger&rsquo;s web hosting plans<\/strong> at no additional cost.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hostinger has reduced server response times by up to 35% after optimizing its in-house content delivery network (CDN).
