Gperftools
gperftools is a collection of specialized tools for profiling CPU usage, detecting memory errors, and providing high-performance memory allocation. It provides a memory profiling toolkit for C++ applications, including a sampling CPU profiler and a heap profiler for analyzing consumption patterns.
The project includes a high-performance memory allocator designed as a multi-threaded replacement for standard allocation to reduce contention and improve execution speed. It further provides a memory debugger to identify illegal memory access and double frees.
The toolkit covers broad diagnostic capabilities for detecting memory leaks and processor bottlenecks. This includes heap memory analysis, CPU usage profiling through stack trace capture, and general memory error detection.
Features
- CPU Profilers - Provides a sampling profiler that identifies processor-intensive functions and execution bottlenecks through stack trace analysis.
- Heap Analyzers - Provides a tool that tracks memory allocations to identify leaks and analyze heap consumption patterns.
- High Performance Allocators - Implements a multi-threaded memory allocator optimized for execution speed, scalability, and reduced contention.
- Allocation Registries - Maintains a registry of all active memory allocations to identify blocks that were never released.
- Memory Profilers - Provides a heap profiler that tracks memory allocations to identify consumption patterns and resource leaks.
- Memory Profilers - Offers a comprehensive suite for analyzing CPU performance and heap memory usage in C++ applications.
- Memory Allocation Debuggers - Provides a diagnostic tool that detects double frees and illegal memory access to prevent heap corruption.
- Statistical Profilers - Uses periodic interrupts to capture call stacks and identify the most frequent processor hotspots.
- Memory Leak Detection - Tracks memory allocations and deallocations to find unreachable memory and prevent resource exhaustion.
- Memory Instrumentation - Captures stack traces and detects double frees or illegal memory access to resolve critical stability bugs.
- Runtime Call-Stack Capturers - Captures active execution frames to map memory allocations and performance hotspots to specific source code locations.
- Native Stack Unwinders - Implements native stack unwinding to map memory allocations and CPU hotspots back to specific source code locations.
- Heap Corruption Detection - Profiles memory consumption patterns and monitors heap activity to detect corruption and double frees.
- Paged Memory Management - Organizes memory into fixed-size pages and spans to minimize fragmentation and simplify large allocation tracking.
- Symbol Interposition - Overrides standard library memory functions using linker tricks or environment variables to inject custom allocation logic.
- Allocator Local Caches - Reduces lock contention by managing a private pool of memory for each thread before requesting global heap access.
- System Diagnostics - High-performance memory allocation and performance analysis tools.
- Systèmes de build - A collection of tools for measuring and improving performance.
- Command Line Tools - Listed in the “Command Line Tools” section of the The Book Of Secret Knowledge awesome list.
- Outils de développement - Utilities for measuring and improving application performance.
- Windows Environments - Listed in the “Windows Environments” section of the Awesome C awesome list.
