Today we're excited to announce what we began to plan more than two years ago: the 1.1.1.1 App with WARP performance and security technology. We built Warp from the ground up to thrive in the harsh conditions of the modern mobile Internet.
Not long ago I needed to benchmark the performance of Golang on a many-core machine. I took several of the benchmarks that are bundled with the Go source code, copied them, and modified them to run on all available threads.
You log in to a Linux server with a performance issue: what do you check in the first minute?
Cloudflare investigated CPU performance benchmark results for Workers, uncovering and fixing issues in infrastructure, V8 garbage collection, and OpenNext optimizations. These improvements have made Cloudflare Workers faster for all customers.
Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. PTP’s predecessor, Network Time Protocol (…
We announced support for HTTP/3, the successor to HTTP/2, during Cloudflare’s birthday week last year. Our goal is and has always been to help build a better Internet. Even though HTTP/3 is still in draft status, we've seen a lot of interest from our users.
It is no secret that we at CloudFlare love Go. We use it, and we use it a LOT. There are many things to love about Go, but what I personally find appealing is the ability to write assembly code!
webpack is a brilliant tool for bundling frontend assets. When things start to slow down, though, its batteries-included nature and the ocean of third-party tooling can make it difficult to optimize. Poor performance is the norm and not the exception. But it doesn’t have to be that way, and so — after many hours of research, trial,…
We’re sharing details about Strobelight, Meta’s profiling orchestrator. Strobelight combines several technologies, many open source, into a single service that helps engineers at Meta improve effic…
How we fully migrated github.com away from CSS-in-JS. The post Improving site performance by shipping more CSS appeared first on The GitHub Blog.

High-performance applications form the backbone of the modern web. At LinkedIn, a number of internal high-throughput services cater to thousands of user requests per second. For optimal user experience, it is very important to serve these requests with low latency. For example, a product our members
We are open-sourcing DCPerf, a collection of benchmarks that represents the diverse categories of workloads that run in data center cloud deployments. We hope that DCperf can be used more broadly b…
What it is: FioSynth is a benchmark tool used to automate the execution of storage workload suites and to parse results. It contains a base set of block level storage workloads, synthesized from pr…
At the beginning of this year, we ran several experiments aimed at reducing the latency impact of the Ruby garbage collector (GC) in Shopify's monolith. In this article, Jean talks about the changes we made to improve GC performance, and more importantly, how we got to these changes.
We’ve spent a lot of time on performance tuning our Apache Flink application. We’ll walk you through key lessons for optimizing large stateful Apache Flink applications
Shopify’s Data Reliability team built custom verification, benchmarking, and profiling tooling for testing and analyzing Trino. Our tooling is designed to minimize the risk of various changes at scale.
We’re open-sourcing Rebalancer, the assignment-problem solver that has been used to solve resource allocation problems throughout Meta for over nine years. Rebalancer separates several related concerns: how to specify an assignment problem, how to store it efficiently in memory, how to solve it, and how to debug it. This separation of concerns is crucial to [...] Read More... The post Open-Sourcing Rebalancer: A Generic, High-Performance Library for Solving Assignment Problems appeared first on Engineering at Meta.
Workers KV Instant delivers sub-2ms p99 read latencies and 250ms global replication across Cloudflare’s 300+ edge locations. KV Instant eliminates cold-read penalties and uses the familiar Workers KV API.
