Recapping Speed Week 2023

Speed Week 2023 is officially a wrap.

In our Welcome to Speed Week 2023 blog post, we set a clear goal:

“This week we will help you measure what matters. We’ll help you gain insight into your performance, from Zero Trust and API’s to websites and applications. And finally we’ll help you get faster. Quickly.”.

This week we published five posts on how to measure performance, explaining which metrics and approaches make sense and why. We had a deep dive on the latest Core Web Vital, “Interaction to Next Paint”, what it means and how we can help. There was a post on Time To First Byte (TTFB) and why it isn't a good way to measure good web performance. We also wrote about how to measure Zero Trust performance, and announced the Internet Quality page of Cloudflare Radar - giving everyone the ability to compare Internet connection quality across Internet Service Providers, countries, and more.

We launched new products such as Observatory, Digital Experiencing Monitoring and Timing Insights. These products give an incredible window into how your applications and websites are performing through the eyes of website visitors and your employees.

Next, we showed how we continue to be the fastest, with fresh posts on how we have the fastest network, fastest Secure Web Gateway, fastest Zero Trust Network Access and fastest Remote Browser Isolation solutions. There was even an update on how our global network grew to 300 cities. The Cloudflare network is at the center of everything we do, and every product we build benefits from the speed and scale it provides and the proximity to the user.

There were also a number of great product announcements which make speed simple, single button performance boosts to accelerate your traffic. Smart Hints, HTTP/3 Prioritization, Argo for UDP, Brotli end-to-end, LL-HLS for Stream and Ricochet for API Gateway all make speed simple - giving you an immediate speed boost on your traffic for very minimal, if any configuration.

We also showed how AI / ML continue to play a big part at Cloudflare, with posts discussing why running AI inference on Cloudflare's network makes performance sense, and how we both scale and run machine learning at the microseconds level.

Finally, we wrote about how we are making it easier than ever for customers to migrate to Cloudflare from legacy vendors via our Turpentine and Descaler programs.

We’re on a mission to be the fastest at everything we do, and to make it simple for our customers to get the best performance.

In case you missed any of the announcements, take a look at the summary and navigation guide below.

Announcement	Summary
Globally distributed AI and a Constellation update	Announcing new Constellation features, explaining why it’s the first globally distributed AI platform and why deploying your machine learning tasks in our global network is advantageous.
Every request, every second: scalable machine learning at Cloudflare	Describing the technical strategies that have enabled us to expand the number of machine learning features and models, all while substantially reducing the processing time for each HTTP request on our network.
How Orpheus automatically routes around bad Internet weather	A little less than two years ago, Cloudflare made Orpheus automatically available to all customers for free. Since then, Orpheus has saved 132 billion Internet requests from failing by intelligently routing them around connectivity outages, prevented 50+ Internet incidents from impacting our customers, and made our customer’s origins more reachable to everyone on the Internet. Let’s dive into how Orpheus accomplished these feats over the last year.
How Cloudflare runs machine learning inference in microseconds	How we optimized bot management’s machine learning model execution. To reduce processing latency, we've undertaken a project to rewrite our bot management technology, porting it from Lua to Rust, and applying a number of performance optimizations. This post focuses on optimizations applied to the machine-learning detections within the bot management module, which account for approximately 15% of the latency added by bot detection. By switching away from a garbage collected language, removing memory allocations, and optimizing our parsers, we reduce the P50 latency of the bot management module by 79μs - a 20% reduction.

Announcement	Summary
Spotlight on Zero Trust: we're fastest and here's the proof	Cloudflare is the fastest Secure Web Gateway in 42% of testing scenarios, the most of any provider. Cloudflare is 46% faster than Zscaler, 56% faster than Netskope, and 10% faster than Palo Alto for ZTNA, and 64% faster than Zscaler for RBI scenarios.
Understanding end user-connectivity and performance with Digital Experience Monitoring, now available in beta	DEX allows administrators to monitor their WARP Deployment and create predefined application tests. Features include live team & device analytics, server and traceroute tests, Synthetic Application Monitoring, and Fleet Status for real-time insights on WARP deployment.
Descale your network with Cloudflare’s enhanced Descaler Program	The speed at which customers are able to move from Zscaler ZIA to Cloudflare Gateway continually gets faster. It usually takes more time to set up a meeting with the right technical administrators than to migrate settings, configurations, lists, policies and more to Cloudflare.
Donning a MASQUE: building a new protocol into Cloudflare WARP	Announcing support for MASQUE, a cutting-edge new protocol for the beta version of our consumer WARP iOS app.
How we think about Zero Trust Performance	There are many ways to view network performance. However, at Cloudflare we believe the best way to measure performance is to use end-to-end HTTP response measurements. In this blog, we’re going to talk about why end-to-end performance is the most important thing to look at, why other methods like proxy latency and decrypted latency SLAs are insufficient for performance evaluations, and how you can measure your Zero Trust performance like we do.

Announcement	Summary

But wait – maybe you've heard that you should stop worrying about TTFB? Isn't Cloudflare moving away from TTFB as a metric? Read on to understand why there are still situations where TTFB matters.
Are you measuring what matters? A fresh look at Time To First Byte	Time To First Byte (TTFB) is not a good way to measure your websites performance. In this blog we’ll cover what TTFB is a good indicator of, what it's not great for, and what you should be using instead.
INP. Get ready for the new Core Web Vital	On May 10, 2023, Google announced that INP will replace FID in the Core Web Vitals in March 2024. The Core Web Vitals play a role in the Google Search algorithm. Website owners who care about Search Engine Optimization (SEO) should prepare for the change. In this post we outline what INP is, and how you can prepare.
