Speed your code with the GNU profiler. Introduction The performance needs of software vary, but it's probably not surprising that many applications have very stringent speed requirements. Video players are a good example: a video player is not much use if it can only play a video at 75 percent of the required speed. Other applications, such as video encoding, are lengthy operations that are best run "batch" style, where you start a job and leave it running while you go do something else.
Although these types of applications don't have such hard performance limits, increasing speed will still bring benefits, such as being able to encode more videos over a given period and being able to encode at a higher quality in the same time. In general, for all but the simplest applications, the better the performance, the more useful and popular the application will be. For this reason, performance considerations are (or should be) in the forefront of many application developers' minds. gprof to the rescue Make the software work correctly.

Update: Version 2.0 is up! There are now 4 versions to chose from: (If you are wondering what the differences are between the screen and print: the screen has less color variations, and no gradients to make it easier to read.) One designed for on-screen reading: PDF (Excel 2011 source),One designed for hard-copy reading: PDF (Excel 2011 source),One designed for monochrome printing: PDF (Excel 2011 source), andOne designed for Red/Green color bindness -- a "Blue" theme PDF (Excel 2011 source). The color coded Legend / Keys helps provide guidance for your experience level. Green = Essential Yellow = Basic Orange / Blue = Advanced Red = Expert If you don't like this version (I'd love to hear why) try these, you may find them more to your liking...
