BPF Performance Toolsを読んだので、感想ブログです。 先に感想を言っておくと「最高」でした。 BPF Performance Toolsとは? NetflixでKernel・パフォーマンスにかかわるチューニング・アーキテクチャを専門にしているBrendan Greggさんが書いた本です。BPFのiovisorというTracing分野の第一人者でもあります。 www.brendangregg.com 2019年12月に発売したばかりなので、BPFの分野では最新の本でしょう。他の著書に有名な本として(日本語版の)「詳解システム・パフォーマンス」があります。 BPF Performance Toolsは「詳解システム・パフォーマンス」第二弾と言えるかもしれません。ちなみにページ数は880Pあり、Kindleで表示される読み終わるための平均的な時間は「27時間30分」で、大作R

MySQL is certainly a powerful open source database management system, but even the most robust engine struggles when queries take an eternity to execute. For DBAs and developers, improving MySQL query performance is an ongoing goal. Efficient query performance is crucial for ensuring the smooth operation and optimal user experience of applications powered by MySQL databases. When businesses rely h

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. Collaborating on standards is a big part of that, and we're very fortunate to do that here. Even though HTTP/3 is still in draft status, we've seen a lot of interest from our users. So far, over 113,000 zones have activated HTTP/3 an
Flutter vs React Native vs Native: Deep Performance Comparison The Story Behind the Research As a custom software development company, inVerita and its mobile development team continuously dig into the performance of cross-platform mobile solutions available on the market, that’s how Flutter vs React Native vs Native Part I emerged. Yes, it was quite controversial as one can state we weren’t using
Amazon Web Services ブログ 初めてのPerformance Insights入門 テクニカルソリューションアーキテクトの笹川です。 本記事ではRDS MySQL使用時のPerformance Insightsの使い方についてご紹介させて頂きます。 Performance Insightsを聞いたことがあるけれど何ができるのか分からない、実際にどのように活用すれば良いのかイメージができないという方もいらっしゃるのではないでしょうか。今回は初めてのPerformance Insights入門と題してサンプルのクエリを実行しながらPerformance Insightsの使い方をご紹介していきます。 Performance InsightsとPerformance Schema Performance InsightsではDBの負荷状況がMySQLにログインすることなくAWS
Performance comparison: counting words in Python, Go, C++, C, AWK, Forth, and Rust March 2021 Summary: I describe a simple interview problem (counting frequencies of unique words), solve it in various languages, and compare performance across them. For each language, I’ve included a simple, idiomatic solution as well as a more optimized approach via profiling. Go to: Constraints | Python Go C++ C
CSS-in-JS has taken a solid place in front-end tooling, and it seems this trend will continue in the near future. Especially in the React world. For example, out of 11492 people who participate in State of CSS survey in 2020 only 14.3% didn’t hear of Styled Components (a dominant CSS-in-JS library). And more than 40% of participants have used the library. I wanted to see an in-depth performance co
Talk by Brendan Gregg for USENIX LISA 2019: Linux Systems Performance. Abstract: " Systems performance is an effective discipline for performance analysis and tuning, and can help you find performance wins for your applications and the kernel. However, most of us are not performance or kernel engineers, and have limited time to study this topic. This talk summarizes the topic for everyone, touring
Orbit, the Open Runtime Binary Instrumentation Tool is a standalone native application profiler for Windows and Linux. It supports native applications written in languages such as C, C++, Rust, or Go. Its main purpose is to help developers identify the performance bottlenecks of a complex application. Orbit can be also used to visualize the execution flow of such applications. The key differentiat

Learn how concurrent features like Transitions, Suspense, and React Server Components improve application performance. React 18 has introduced concurrent features that fundamentally change the way React applications can be rendered. We'll explore how these latest features impact and improve your application's performance. First, let's take a small step back to understand the basics of long tasks a
Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even the
Let’s compare the performance of all supported runtimes + 2 custom runtimes (Rust and GraalVM). Will compare cold start and warm.

I’ve used Google Fonts in prototypes and in 10M+ MAU products. It’s incredibly easy to get started with and provides an amazing font discovery. That’s also why it’s currently still used on over 42M websites! This convenience has its price: Performance. Many have already pointed out the cost of multiple requests. If you want the remaining speed boost, then you’re best off downloading your used Goog

January 02, 2020 Performance testing HTTP/1.1 vs HTTP/2 vs HTTP/2 + Server Push for REST APIs When building web services, a common wisdom is to try to reduce the number of HTTP requests to improve performance. There are a variety of benefits to this, including less total bytes being sent, but the predominant reason is that traditionally browsers will only make 6 HTTP requests in parallel for a sin

# OverviewIn this post I will use a simple HTTP benchmark to do a head-to-head performance comparison between the Linux kernel's network stack, and a kernel-bypass stack powered by DPDK. I will run my tests using Seastar, a C++ framework for building high-performance server applications. Seastar has support for building apps that use either the Linux kernel or DPDK for networking, so it is the per
はじめに 「サイト表示が 0.1 秒遅くなると、売り上げが 1%減少し、1 秒高速化すると 10%の売上が向上する。」こんな鉄板フレーズがある通り、サイトの表示速度はユーザー体験や売り上げに直結するもので、早ければ早いだけ嬉しいです。 パフォーマンスの問題は小さな問題が絡み合って大きな問題になっていたりして、特定が難しいですが、Performance Insightsを使うと、問題になりそうな部分を簡単に分析することができます。 今回はこの機能を使ってページ読み込みパフォーマンスの問題を計測、改善する方法について書いていきたいと思います。 Performance Insights とは ページ読み込みの分析に特化しているパフォーマンスパネルです。 分析したいページのFCPタイミングやLCPのタイミング、CLSがどこで起きたかなど、Lighthouseの指標に近い目線でページの読み込みを細か
