  5. 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. Zoom analyzes and annotates your source and assembly code with specific tuning advice for many compilers and processors. Zoom saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. It also supports remote network profiling and scripting. This version includes several improvements: * Added ability to hide self and total columns in hotspot view * Fixed to allow installation on unknown Linux distributions * Fixed installer to operate from /tmp * Fixed installer to check for compatible platform * Fixed problem with resolution of vmlinux symbols on some platforms * Fixed determination of release name on some Linux distros * Improved UI responsiveness for profiles containing many processes * Improved zoom daemon support on localhost http://www.rotateright.com

Zoom saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. It also supports remote network profiling and scripting. Highlights in Zoom v1.6.1: * Added ability to specify client port and address for remote profiling * Added version check when opening a profile * Added work-around for GTK 2.18 incompatibility * Added support for user space CPUFreq governor * Fixed possible hang during sample processing * Fixed potential crash when searching for text in symbol lists * Fixed bug with virtual machine detection * Fixed to allow profiling with SELinux enabled (manual driver load) * Fixed driver identification of Intel Core i5/i7 (Lynnfield) Zoom is available at: http://www.rotateright.com
