Amazon Web Services ブログ 初めてのPerformance Insights入門 – その3 テクニカルソリューションアーキテクトの笹川です。 前回は初めてのPerformance Insights入門 – その2 と題してPerformance Insightsと拡張モニタリングを使ってデータベースのパフォーマンスチューニングを行ってみました。パフォーマンスチューニングをする際に何を手がかりにどう確認していくのか、少しでもイメージを掴んで頂けていたら幸いです。今回も引き続き、色々なシナリオを検討しながらPerformance Insightsを使ってパフォーマンスチューニングを行ってみたいと思います。 検証環境と注意事項 本記事では下記の環境で検証を行なっていきます。 RDS MySQL8.0.23 db.m3.medium (1vCPU, メモリ3.75GiB) プ
CI for performance: Reliable benchmarking in noisy environments
CI for performance: Reliable benchmarking in noisy environments by Itamar Turner-Trauring Last updated 23 Oct 2022, originally created 02 Dec 2020 You have some code—whether it’s Python, Rust, Java, or some other language—whose speed you want to measure over time. Ideally you want it to get faster, but at the very least you don’t want to get any slower. So you write a benchmark, and now you need t

Reasons why SELECT * is bad for SQL performance - Tanel Poder Consulting
Here’s a list of reasons why SELECT * is bad for SQL performance, assuming that your application doesn’t actually need all the columns. When I write production code, I explicitly specify the columns of interest in the select-list (projection), not only for performance reasons, but also for application reliability reasons. For example, will your application’s data processing code suddenly break whe
