gprofng: The Next Generation GNU Profiling Tool
summary
gprofng is a sampling profiler (default 10 ms sampling) that collects profiles from unmodified Linux binaries — no recompilation or instrumentation — and shows function, source line and disassembly views. It supports gcc-built C/C++ plus Java and Scala, runs on Intel, AMD and Arm, handles shared libraries and POSIX/OpenMP/Java threads, and archives experiment directories. It can compare profiles (ratios/deltas) to spot regressions; a GUI and HTML browser are in progress and binutils inclusion is approved.
