  "github_readme_excerpt": "# Async-profiler\n\nThis project is a low overhead sampling profiler for Java\nthat does not suffer from the [Safepoint bias problem](http://psy-lob-saw.blogspot.ru/2016/02/why-most-sampling-java-profilers-are.html).\nIt features HotSpot-specific API to collect stack traces\nand to track memory allocations. The profiler works with\nOpenJDK and other Java runtimes based on the HotSpot JVM.\n\nUnlike traditional Java profilers, async-profiler monitors non-Java threads\n(e.g., GC and JIT compiler threads) and shows native and kernel frames in stack traces.\n\nWhat can be profiled:\n\n- CPU time\n- Allocations in Java Heap\n- Native memory allocations and leaks\n- Contended locks\n- Hardware and software performance counters like cache misses, page faults, context switches\n- and [more](docs/ProfilingModes.md).\n\nSee our [3 hours playlist](https://www.youtube.com/playlist?list=PLNCLTEx3B8h4Yo_WvKWdLvI9mj1XpTKBr)\nto learn about more features.\n\n# Download\n\n### Stable release: [4.4](https://github.com/async-profiler/async-profiler/releases/tag/v4.4)\n\n- Linux x64: [async-profiler-4.4-linux-x64.tar.gz](https://github.com/async-profiler/async-profiler/releases/download/v4.4/async-profiler-4.4-linux-x64.tar.gz)\n- Linux arm64: [async-profiler-4.4-linux-arm64.tar.gz](https://github.com/async-profiler/async-profiler/releases/download/v4.4/async-profiler-4.4-linux-arm64.tar.gz)\n- macOS arm64/x64: [async-profiler-4.4-macos.zip](https://github.com/async-profiler/async-profiler/releases/download/v4.4/async-profiler-4.4-macos.zip)\n- Profile converters: [jfr-converter.jar](https://github.com/async-profiler/async-profiler/releases/download/v4.4/jfr-converter.jar)\n\n### Nightly builds\n\n[The most recent binaries](https://github.com/async-profiler/async-profiler/releases/tag/nightly) corresponding\nto the latest successful commit in `master`.\n\nFor a build corresponding to one of the previous commits, go to\n[Nightly Builds](https://github.com/async-profiler/async-profiler/actions/workflows/test-and-publish-nigh",
