Spring Boot Memory Performance - DZone
It has sometimes been suggested that Spring and Spring Boot are “heavyweight,” perhaps just because they allow apps to punch above their weight, providing a lot of features for not very much user code. In this article we concentrate on memory usage and ask if we can quantify the effect of using Spring? Specifically we would like to know more about the real overhead of using Spring compared to othe

PGCon 2015 で計算機システムの性能評価について講演してきました - は
カナダのオタワ大学で開催されたPGCon 2015で、"The Art of Performance Evaluation" という題目で、計算機システム、とくにデータベースシステムに関する性能評価の基礎となる考え方と、基本となる3つの技能（モデリング、測定、シミュレーション）に関して講演を行ってきました。 PGConはPostgreSQL関係者の集う最もハイレベルなカンファレンスの一つで、世界中からPostgreSQLの主要開発者が集い、PostgreSQLの開発方針を議論したり、最新のPostgreSQLに関する技術動向が話し合われる場となっています。 PostgreSQLの開発や使い方など比較的具体論が取り扱われることが多い中、自分の講演はやや異色な発表ではありましたが、システムソフトウェアの開発において正しい性能評価の考え方を知ることは欠くことのできない重要な技能であるので、その点
『アメーバピグにおけるDB構成&対応記』
2ヶ月前にインフルエンザとウィルス性胃腸炎でひどくダメージを受けた増田(@masudaK)です。アメーバピグは2009年2月に始まったサービスで、FLASH・Javaで作られています。そして、データストアにMySQLを用いてます。本記事では、わたくしが2年ほど見続けているアメーバピグのDB環境について構成や、日々どのようにして問題と向き合っているかを紹介したいと思います。インフラ寄りの内容が多いため、アプリ寄りの話は弊社生沼の資料を御覧ください。 1. 構成と規模 1.1. 構成 まず構成ですが、読み書きはすべてマスターへ行うようにしています。そのため、スレーブには参照を向けず、ホットスタンバイとして使っています。バージョンに関しては2012年中旬までは5.0を使ってましたが、DC移転にあわせて5.5にあげました。ロック機能を用いたシャード構成をしてまして、2014年3月現在6シャードにな
