ユニコーンを目指すスタートアップのパフォーマンス改善 木村和貴氏(以下、木村):ありがとうございます。それでは準備ができましたので、三木さんよろしくお願いいたします。 三木明氏(以下、三木):はい、よろしくお願いいたします。僕がパワーポイントでのマウス操作が超苦手なので、今日は「GitPitch」を使わせていただいています。「Performance Hack 101」ということで、パフォーマンス改善方法を自己紹介ついでに話したいと思います。よろしくです。こんちわーす! 会場:こんちわーす! 三木:あざーす! みなさんのパフォーマンスが高いので、この時間に来れるってすばらしい。 僕はRepro(リプロ)の三木っていいます。左を見ていただくとわかるけど、スタートアップを立ち上げたり、いろいろと失敗したりしているいわゆるスタートアップおじさんです。今Reproの創業者兼CTO、VPoEをやってい
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

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

日本人の三分の一は日本語が読めないそうですね。※1 日本人の三分の一は日本語が読めないということであるなら、極めて単純に考えると 公務員の三分の一は日本語が読めないでしょうし、 新宿駅の乗降客の三分の一も日本語が読めないでしょうし、 ディズニーランド来場者の三分の一も日本語が読めないでしょうし、 プロゲーマーの三分の一も、やっぱり日本語が読めないのでしょうか。 ”ゲームライター”ちょもす氏のインタビューが、いろいろと話題です。 https://wellplayed.media/interview-chomosh-20190814/ 前後編通して面白いので是非読んで欲しいのですが、話題となっているポイントはここです。 ――実際、プロゲーマーになる人ってどういう人だと思っていますか? ちょもす: 医者、教授、社長の息子。 これはプロゲーマーに限りませんが、ゲーム業界で表舞台に立つ人がそれなりの

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
CircleCI (Performance Plan) vs. Github Actions 結論: CircleCI を買おう 現在ユビレジでは CI は CircleCI (Performance Plan)と TravisCI を使っていて、 CircleCI: サーバーサイド(いろんな言語がある) Web フロントエンド(Rails アプリのなかで webpack が動いていたり、 create-react-app で作られたペラっとしたものがあったりいろいろある) TravisCI: iOS アプリ というような感じで使い分けている。 Performance Plan なんだから iOS のも Travis から引っ越せばいいんじゃねえの?と思わんでもないのだが、 Travis の annual 課金がまだ残ってる iOS の CI と TravisCI と CircleCI に
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
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
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
How React 18 Improves Application PerformanceLearn 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

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

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

BPF Performance Tools: Linux System and Application Observability (book) 15 Jul 2019 BPF (eBPF) tracing is a superpower that can analyze everything, and I'll show you how in my upcoming book BPF Performance Tools: Linux System and Application Observability, coming soon from Addison Wesley. The book includes over 150 BPF observability tools that you can run to find performance wins and troubleshoot
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
