async-profiler
A low overhead sampling profiler for Java that avoids safepoint bias and supports CPU, heap, and native memory profiling.
What is async-profiler?
Async-profiler is a low overhead sampling profiler for Java applications that avoids safepoint bias, a common problem in traditional profilers. It supports profiling CPU time, heap allocations, native memory, lock contention, and performance counters, providing accurate performance data with minimal impact on the application. The tool works with OpenJDK and other HotSpot-based JVMs, offering features like kernel and native frame visibility.
Java developers, performance engineers, and DevOps professionals who need to diagnose performance issues, memory leaks, or lock contention in production or development environments. It is particularly useful for those working with high-performance or resource-intensive Java applications.
Developers choose async-profiler for its low overhead and accuracy, as it avoids safepoint bias and provides insights into native memory and non-Java threads. Its support for multiple profiling modes and integration with tools like FlameGraph makes it a versatile and reliable choice for performance analysis.
