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
This talk discusses Linux profiling using perf_events (also called "perf") based on Netflix's use of it. It covers how to use perf to get CPU profiling working and overcome common issues. The speaker will give a tour of perf_events features and show how Netflix uses it to analyze performance across their massive Amazon EC2 Linux cloud. They rely on tools like perf for customer satisfaction, cost o

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. Â For many years the increase in speed of our processors has greatly outstripped latency gains to main-memory. Â Bandwidth to main-memory has greatly increased via wider, and multi-channel, buses however the latency has not significantly reduced. Â 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

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
