Perf Book
The book "Performance Analysis and Tuning on Modern CPU"
This project is a practical guide to performance analysis and tuning on modern CPUs, bridging microarchitecture details with hands-on profiling. It explains how caches, TLBs, prefetchers, branch predictors, and out-of-order execution influence real program speed, then connects those concepts to concrete optimization strategies. Readers learn how to design trustworthy benchmarks, avoid measurement traps (warmup, turbo, frequency scaling), and interpret hardware performance counters. The book... -

Hotspot
The Linux perf GUI for performance analysis
This project is a KDAB R&D effort to create a standalone GUI for performance data. As the first goal, we want to provide a UI like KCachegrind around Linux perf. Looking ahead, we intend to support various other performance data formats under this umbrella. The main feature of the hotspot is visualizing a perf.data file graphically. The timeline allows filtering the results by time, process, or thread. The data views will update accordingly. You can also launch perf from the hotspot, to profile a newly started application, or to attach to an already running process(es). ... -

Honggfuzz
Security oriented software fuzzer
...It supports multiple fuzzing modes—stdin, file, and networking—so targets can be exercised the same way they run in production. Instrumentation via compiler hooks or hardware/perf counters guides mutations toward previously unseen edges, while persistent mode keeps the target process alive to amortize startup costs. The tool integrates tightly with sanitizers and can attach to already running processes, making it convenient for both white-box and black-box fuzzing. When it finds a crash, honggfuzz captures detailed context, minimizes the input, and can pin reproducibility by controlling CPU affinity and resource limits. ... -

Padrões de commits
Reference project for creating clear, standardized Git commit messages
...It explains semantic commit conventions and how structured messages make project history easier to understand and automate. The guide covers common types such as feat, fix, docs, test, build, perf, style, refactor, chore, and ci. It pairs many commit categories with emojis for quick visual identification. The repository also includes a commit-msg shell hook that can validate messages against Conventional Commits rules. Additional sections provide message examples, Git command references, commit body and footer guidance, and a glossary for common collaboration concepts. -

node-in-debugging
Node.js Debugging Guide
Node.js Debugging Guide is a Chinese-language technical book and repository about diagnosing performance, memory, code, and production problems in Node.js. Its CPU section introduces Linux perf, FlameGraph, V8 profiling, and the Tick Processor. Memory chapters cover core dumps, llnode, heap snapshots, leak detection, and CPU or memory monitoring. Code-level material examines promises, async and await, stack traces, the event loop, native Rust add-ons, and uncaught exceptions. Tooling lessons use source maps, Chrome DevTools, Visual Studio Code, debugging modules, REPL utilities, and hot reload. ... -

perf-tools
Performance analysis tools based on Linux perf_events and ftrace
A miscellaneous collection of in-development and unsupported performance analysis tools for Linux ftrace and perf_events (aka the "perf" command). Both ftrace and perf are core Linux tracing tools, included in the kernel source. Your system probably has ftrace already, and perf is often just a package add. These tools are designed to be easy to install (fewest dependencies), provide advanced performance observability, and be simple to use: do one thing and do it well. ... -

AvalonJs
An elegant efficient express mvvm framework
Index.html, index1.4.html, index-ng.html, index-vue.html, index-react.html in the perf directory of the test page. If there is a large table or list on the page, other frames will get stuck when the browser loads the page (white screen), while avalon is much smoother. Avalon 2.1.5 supports back-end rendering. The attribute value must be enclosed in double quotes, the label name must be lowercase, and the label must be closed (normally closed, or self-closed). -

Mi-perf
Miperf is an automated enhancement of iperf tool
iperf is a tool that can create TCP&UDP data streams and measure the throughput of a network that is carrying them. basically to do this iperf testing, we need 2 machines to act as server and client. we run a command -s in server side and then launch a client connection to a server by typing a command -c in client side. before that we need to enter the webgui of the wifi AP to do some configurations such as, change the frequency mode and channel. so we need to repeat the same process/steps... -
