Compression

Could we get more cache space with the same hardware? We prototyped compression inside Cloudflare's cache to find out.

Today, we’re excited to give you a sneak peek of our support for shared compression dictionaries, show you how it improves page load times, and reveal when you’ll be able to try the beta yourself.

Cloudflare's customers can now take advantage of Zstandard (zstd) compression, offering 42% faster compression than Brotli and 11.3% more efficiency than GZIP. We're further optimizing performance for our customers with HTTP/3 prioritization and BBR congestion control, and enhancing privacy through Encrypted Client Hello (ECH).

Today, we're enhancing our support for Brotli compression, enabling end-to-end Brotli compression for web content. Compression plays a vital role in reducing bytes during transfers, ensuring quicker downloads and seamless browsing

Using the brotli dictionary to improve compression of web content without sacrificing performance.

Compression is often considered an essential tool when reducing the bandwidth usage of internet services. The impact that the use of such compression schemes can have on security, however, has often been overlooked.

We believe the true dream of cloud computing is that your code lives in the network itself. Your code doesn't run in "us-west-4", it runs everywhere.

How Cloudflare was able to save hundreds of gigabits of network bandwidth and terabytes of storage from Kafka.

One of the nicer perks I have here at Cloudflare is access to the latest hardware, long before it even reaches the market. Until recently I mostly played with Intel hardware.

Cloudflare has an automatic image optimization feature called Polish, available for paid plan users. It recompresses images and stripping excess data, speeding up delivery to browsers.

Compression is one of the most important tools CloudFlare has to accelerate website performance. Compressed content takes less time to transfer, and consequently reduces load times.

Some months ago, we made a big bet on partnering with CloudFlare for performance improvements and website security for our Magento hosting customers. Customer experience is core to our business and relying on another company is a major deal.

Three years ago we launched Railgun, CloudFlare's origin network optimizer. Railgun allows us to cache the uncacheable to accelerate the connection between CloudFlare and our customers' origin servers.

Recently I was contacted by Dr. Igor Kozin from The Institute of Cancer Research in London. He asked about the optimal way to compile CloudFlare's open source fork of zlib.

A few years ago Google made a proposal for a new HTTP compression method, called SDCH (SanDwiCH). The idea behind the method is to create a dictionary of long strings that appear throughout many pages of the same domain (or popular search results).

With the widespread adoption of high bandwidth Internet connections in the home, offices and on mobile devices, limitations in available bandwidth to download web pages have largely been eliminated.
