Tutorial: Profiling Rust applications in Docker with perf | Blog | Guillaume Endignoux
With Moore’s law coming to an end, optimizing code to avoid performance pitfalls is becoming more and more useful. To this end, programming languages like Rust are designed to produce fast and memory-efficient programs out-of-the-box. When that is not sufficient, profilers like perf are useful to measure where the code is slow and therefore which algorithms and data structures should be optimized.
Linux Profiling at Netflix
Talk for SCaLE13x. Video: https://www.youtube.com/watch?v=_Ik8oiQvWgo . Profiling can show what your Linux kernel and appliacations are doing in detail, across all software stack layers. This talk shows how we are using Linux perf_events (aka "perf") and flame graphs at Netflix to understand CPU usage in detail, to optimize our cloud usage, solve performance issues, and identify regressions. This

Memory Access Patterns Are Important
In high-performance computing it is often said that the cost of a cache-miss is the largest performance penalty for an algorithm. For many years the increase in speed of our processors has greatly outstripped latency gains to main-memory. Bandwidth to main-memory has greatly increased via wider, and multi-channel, buses however the latency has not significantly reduced. To hide this latency our
perf_events: add support for per-cpu per-cgroup monitoring (v7) [LWN.net]
This series of patches adds per-container (cgroup) filtering capability to per-cpu monitoring. In other words, we can monitor all threads belonging to a specific cgroup and running on a specific CPU. This is useful to measure what is going on inside a cgroup. Something that cannot easily and cheaply be achieved with either per-thread or per-cpu mode. Cgroups can span multiple CPUs. CPUs can be sha

perfの使いかた
概要 Linuxのパフォーマンス解析ツールであるperfの使いかたの紹介 背景 個人的にperfよくできてると思うので紹介したいというのと、 パフォーマンスカウンタの読み方ってあんまり知られてないみたいなので、 それの解説を書きたい。 構成 perf について説明したあと、パフォーマンスカウンタの読みかた、見かた、を説明する。 perfとは何か Linuxに付いてくるプロファイラ。 man perf によると、 NAME ---- perf - Performance analysis tools for Linux と、書いてある。名前がひどいのでなんとかしてほしい。 perf の特徴 個人的には、手軽に使えるのが素晴らしいと思う。 2.6.31以降カーネルに標準で付いてる。(Ubuntuだとlinux-tools-common(TODO:あとで確認)で入るはず) 特殊な設定が必要無く、
Using Performance Counters for Linux – Anton's Blog
The 2.6.31 Linux kernel will add a new performance counter subsystem called Performance Counters for Linux (or perfcounters for short). To use perfcounters, build a kernel with: CONFIG_PERF_COUNTERS=y You will need elfutils and optionally binutils (for c++ function unmangling). On debian or ubuntu: apt-get install libelf-dev binutils-dev The tools must be built 64bit on a 64bit kernel. If you have
Tutorial - Perf Wiki
Introduction Perf is a profiler tool for Linux 2.6+ based systems that abstracts away CPU hardware differences in Linux performance measurements and presents a simple commandline interface. Perf is based on the perf_events interface exported by recent versions of the Linux kernel. This article demonstrates the perf tool through example runs. Output was obtained on a Ubuntu 11.04 system with kernel
Perf Wiki
perf: Linux profiling with performance counters ...More than just counters... Introduction This is the wiki page for the Linux perf command, also called perf_events. perf is powerful: it can instrument CPU performance counters, tracepoints, kprobes, and uprobes (dynamic tracing). It is capable of lightweight profiling. It is also included in the Linux kernel, under tools/perf, and is frequently up
