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

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
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

Performance testing HTTP/1.1 vs HTTP/2 vs HTTP/2 + Server Push for REST APIs
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

Seastar has support for building apps that use either the Linux kernel or DPDK for networking, so it is the per
