GitHub - google/orbit: C/C++ Performance Profiler
This project is not maintained by Google engineers anymore at this point. Orbit, the Open Runtime Binary Instrumentation Tool is a standalone native application profiler for Windows and Linux. It supports native applications written in languages such as C, C++, Rust, or Go. Its main purpose is to help developers identify the performance bottlenecks of a complex application. Orbit can be also used
Valgrind
To use this tool, you must specify --tool=dhat on the Valgrind command line. DHAT is primarily a tool for examining how programs use their heap allocations. It tracks the allocated blocks, and inspects every memory access to find which block, if any, it is to. It presents, on a program point basis, information about these blocks such as sizes, lifetimes, numbers of reads and writes, and read and w
ivarch.com: Pipe Viewer
pv - Pipe Viewer - is a terminal-based tool for monitoring the progress of data through a pipeline and modifying its flow. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion. Data flow rate, error handling st

Luke Stackwalker home page
Introduction A screenshot of Luke Stackwalker displaying profiling results. Luke Stackwalker is a C/C++ code profiler that runs on Windows. It uses call stack sampling to collect profile data, so no code instrumentation is required. Luke Stackwalker can sample the call stack at an user-specified depth to not only provide a display of which functions in the program under test consume most CPU time,

Valgrind
To use this tool, you must specify --tool=massif on the Valgrind command line. Massif is a heap profiler. It measures how much heap memory your program uses. This includes both the useful space, and the extra bytes allocated for book-keeping and alignment purposes. It can also measure the size of your program's stack(s), although it does not do so by default. Heap profiling can help you reduce the
