EverCache Speed and Scalibility

Like any web application, WordPress can be hard to scale. Get traffic spike from a successful social media campaign or getting on the Huffington Post and you’ll start to worry that your server might go down due to the load— at exactly the worst time to fail!

That’s why we built EverCache.

EverCache is one of the most scalable WordPress architectures on Earth. The technology behind EverCache is WP Engine’s proprietary system that moves hundreds of millions of hits per day through our system. Even with a significant traffic spike you can be sure that EverCache will handle it like a champ.

Our customers have been featured on 20/20, Dr. Phil, Huffington Post, TechCrunch, Mashable, HackerNews, and never skipped a beat. We’ve seen individual sites surge to 15,000 simultaneous visitors and EverCache served the traffic without any loss in page-load speed.

EverCache is WP Engine’s “secret sauce” that makes every WordPress site we host incredibly fast, and ridiculously scalable.

Part of the secret is our optional, integrated, full-managed CDN that serves your static content from data centers all around the world, each byte delivered by the server closest to the requesting browser.

Another part of the secret sauce is custom code we developed to connect WordPress events to our super-fast front-end Nginx-based systems. What this means is we can be aggressive about caching your site, while still having responsive updating when a new post goes up, or you deploy new code. Translation: WP Engine is faster and more scalable all the time.  We even added protection from bots that like to crawl your site and blast the backend with pointless requests.

What’s more, if you know your site is going to be especially slammed, we have temporary measures we can put in place to make your site even more scalable and distributed. We used these measures to serve more than 100,000,000 requests in less than 12 hours when the highly trafficked music festival Bonnaroo released their lineup this year. With EverCache, Bonaroo saw zero loss in page load times.
