Show navigation Over the last year the V8 team has developed a new methodology to measure and understand real-world JavaScript performance. We’ve used the insights that we gleaned from it to change how the V8 team makes JavaScript faster. Our new real-world focus represents a significant shift from our traditional performance focus. We’re confident that as we continue to apply this methodology in
2016 - 08 - 12 Dockerホストのパフォーマンスを引き出すTCPカーネルパラメータチューニング Docker Linux もう半年くらいフルDockerでmicroservicesなサービスを運用してるんですが、イマイチパフォーマンスを出し切れていないなという面がありまして、今回Dockerホストの TCP カーネル パラメータを抜本的に見直しました。 そしたら劇的に症状が改善して、 インスタンス 数も削減できた上に安定して メシウマ状態 になったので紹介します。実際効果があったのでチューニングポイントとしてはある程度正解であったと考えていますが、もちろん扱ってるアプリケーションの特性にもよるはずなので一つの ケーススタディ であることをご了承頂ければと。 前提 まずは今回のお話の前提を。こんな環境です。 EC2 c3.xlarge ホストは Ubuntu (EC2 Opt
You log in to a Linux server with a performance issue: what do you check in the first minute? At Netflix we have a massive EC2 Linux cloud, and numerous performance analysis tools to monitor and investigate its performance. These include Atlas for cloud-wide monitoring, and Vector for on-demand instance analysis. While those tools help us solve most issues, we sometimes need to login to an instanc

Speed is a consideration for any website, whether it's for the local barbershop or Wikipedia, with its huge repository of knowledge. It's a feature that shouldn't be ignored. This is why caching is important — a great way to make websites faster is to save parts of them so they don't have to be calculated or downloaded again on the next visit. My team was recently having a discussion about the par
React is very popular at the moment, and I can see why: its developer ergonomics are very attractive. JSX and vDOM are really nice to work with, and it certainly enables composability. But, being the performance-minded person that I am, I wanted to test the claims that it's default-fast. Last updated: 3 Jul 2015 Est.

This document discusses concurrency and parallelism in JavaScript. It begins by distinguishing between concurrency and parallelism, and notes the evolution of web applications towards faster JavaScript. While JavaScript performance has improved, concurrency remains an issue for tasks like image/video processing, games, and communication without blocking the main thread. The document explores using
