Zoom, Low-overhead graphical and command-line profiler.Updated by rotateright on Tuesday, January 29, 2013.
Zoom is a low-overhead graphical and command-line profiler for Linux. A Zoom profile is system-wide, precise down to the instruction level, and captures backtraces. This lets you see exactly what was running, where time was spent, and how that code was called. You can drill down into critical code to get detailed performance data. Zoom analyzes and annotates your code with specific tuning advice for many compilers and processors. Share what you find with colleagues or archive it for later review. Zoom saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. Zoom also supports remote network profiling and scripting.
Platforms: x86, x86_64, ARM or ppc64 Linux
Requirements: Linux with kernel 2.6.9 or later

Fixed option to disable gathering kernel symbols on small systemsUser interface and performance enhancements
Profiling of Mac OS X systems has been added including Time Profile (system-wide), Thread Time Profile and Static Analysis of Mach-O files. Profile data can now be filtered by thread or process. Code Browsers can now load a different source file than was discovered automatically. Bookmark annotations can be added to the Timeline to label points of interests in a profile. x86 system instructions have been added to the integrated instruction reference. Support for Linux 3.5 and later kernels has been added. Power management can now be temporarily disabled during profiling on all kernels.

This release adds x86 instruction help for AVX, FMA, XOP and BMI. Selection of target processes with very large amounts of debug information has been fixed. Westmere EX Xeon processors are now correctly identified. The inability to launch Zoom on systems with misconfigured locale has been fixed as well as an issue with unreadable links in /tmp. A variety of user interface and performance improvements are also included.
