April 11, 2010 Benchmarking in D | ||||
---|---|---|---|---|
| ||||
Hi everyone, I would like to benchmark some of my D routines for performance testing and like to compare it with some alternative implementations in e.g. time and memory consumption. I'm not really experienced in this field and want to ask if someone can share his knowledge. Are there some tools providing by the operating system to look at the performance of a process? Are there any libraries in D that can help? Chris |

On linux, you can do: time foo to get the run time for program foo, including elapsed clock time, time spent in the program itself and time spent in the kernel on behalf of the program (for I/O, mallocs, etc); cat /proc/$(pidof foo)/status to get memory information for a running program. I don't know any way to get the memory information once the program exits. Jerome -- mailto:jeberger@free.fr http://jeberger.free.fr Jabber: jeberger@jabber.fr |

I give a try some of your benchmark suggestions for time measurements. > On what OS?

Otherwise i install a quick unix development environment on a separate partition. Thanks for your replies. Chris -- ruunhb@googlemail.com http://ruuns.de/blog/ |

Hit Ctl-Alt-Del, then click on the "Task Manager" button. One of the tabs gives information about the running processes. You might need to configure the displayed columns, but I don't remember how it's done and I don't have an XP box on hand to check.

On XP, checking Memory Usage will get you most of the way there, although it's not quite as good (it lumps in any working set shared with other processes too). -- ~ My software never has bugs.
