LINE株式会社は、2023年10月1日にLINEヤフー株式会社になりました。LINEヤフー株式会社の新しいブログはこちらです。 LINEヤフー Tech Blog LINE株式会社OA SREチームのhasebeです。 先日、私の担当するプロダクトにてPyroscopeというツールを導入しました。このブログではなぜPyroscopeを導入したのか、導入した結果どういった利点があったのかなどについてご紹介したいと思います。 Pyroscopeとは Pyroscopeとは、Continuous Profilingを実施することができるOSSのツールです。 Profilingについては特に説明は不要でしょう。ざっくりいうと、CPUやメモリ等のリソースをプログラム中のどこが多く消費しているのか(= ボトルネック)を突き止める手法のことを意味します。 一般的には、なにか問題が起きたときに手動でPr
こんにちは、サーバーエンジニアの牧野です。 今回はGoで開発しているアプリケーションでContinuous Profilingを実践するために導入した profefe を紹介したいと思います。 Continuous Profilingとは Continuous Profilingとは、ざっくり言うと本番環境で継続的にプロファイリングすることを指します。Continuous Profilingができると、本番環境でのみ発生するパフォーマンスの問題を捉えることができたり、継続的にプロファイリングすることで問題が発生する前後の状態を比較することができます。 Goには pprof というプロファイリングのための標準パッケージがあり、プロファイリング自体は容易に行うことができますが、Continuous Profilingを実現するとなると、以下のような課題と向き合う必要があります。 本番環境でオー

tl;dr In our continued efforts to expand and improve your profiling experience, we are excited to announce new additions to our language support: Ruby and Python. All the features that are described in this blog post have recently been released as part v0.26.0 of Parca Agent. ~~While currently these language supports are in beta, they can be enabled using the --enable-ruby-unwinding and --enable-p
April 8, 2020 Today, we’ll look at measuring React component render performance with the React Profiler API, measuring interactions with React’s new experimental Interaction Tracing API and measuring custom metrics using the User Timing API. For demonstration purposes, we’ll be using a Movie queueing app. The React Profiler API The React Profiler API measures renders and the cost of rendering to h

Knowing how to profile a React application to improve real-world performance is a good tool in any front-end developer’s toolkit. The Profiler API allows us to do just that with insights on why and how long our components are rendering for. We can use the profiling data to find unnecessary and expensive renders that may be impacting performance negatively. Thankfully, it’s not that complicated. Le
こんにちは、株式会社Techouse バックエンドエンジニアの @nodematerial です。 今回は、RubyKaigi 2024 1日目のセッション「The depths of profiling Ruby」を聴講したので、その内容をブログにまとめさせていただきます。 プロファイラとは プロファイラはコードのパフォーマンスを調べるためのツール全般を指します。 プロファイラには、コードの中で最も遅いところ(ホットスポット)を特定するという大きな役割があります。 Pf2 について スピーカーの osyoyu さんは Pf2 というプロファイラを作成されており、発表ではPf2の実装を中心に解説が行われました。 Pf2 に特徴的な機能 マルチスレッドのプロファイリング GCの所要時間や、GVL によって有効活用できなかった時間を表示することができ、スレッド毎の実行状況の統計を取ることができ

November 1, 2020 It’s historically been difficult for web developers to understand how the JavaScript in their apps performs in a wide range of cirumstances on real user devices. They’ve had to instrument code with poorly performing profiling hooks that could slow down page execution, without having the ability to collect stack samples efficiently. This is where the proposed native JavaScript self

In this post, we are going to use a brand-new (at the time of writing) and still somewhat experimental profiling method in GHC to show how to identify a memory leak and the code causing it. This new profiling method, implemented by Matthew, allows us to map heap closures to source locations. A key feature of this new profiling mode is that it does not require a profiled build (i.e. building with -
The use of templates in C++ programs can sometimes lead to longer builds. C++ Build Insights puts tools at your disposal for analyzing template usage patterns and their associated impact on build time. In this article, we show you how to use the vcperf analysis tool and the C++ Build Insights SDK to understand and fix problematic template patterns. We demonstrate the practical use of these tools t
