Zoom Profiler

Zoom is a low-overhead graphical and command line profiler for Linux. Profiles are system-wide, precise down to the instruction level, and capture complete backtraces of C/C++/ObjC/Fortran/Assembly code. This lets you see exactly where time was spent, what code was running (user or kernel), and how that code was called. Drill down into a specific symbol, and Zoom shows source and assembly annotated with general and processor-specific tuning advice. It saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. This lets you share what you find with colleagues or archive it for later review. Zoom also supports remote network profiling and scripting, making it ideal for embedded or server systems and automated workflows.

Zoom is part of my development environment as much as my compiler. It's easy to install and use on all of my Linux distros. Zoom goes way beyond gprof, oprofile, or sysprof because it has a code view (source and asm) that shows you exactly what's going on down to the line of code.
