Actually, if there's a Perl/Tcl/Python/C/C++/shell hacker running around I could use a decent benchmarking tool to compare stable and current. Basically, what I would like is to be able to do the following: bench -n <number of trials> <command to run> So for example: bench -n 20 buildworld -j4 To run my buildworld script 20 times (with -j4 passed in as an argument to buildworld). I would like the program/script/whatever to collect time -l stats for each iteration. It can simply spit the time -l output to a simple text file in a sensible format (one line per run, with a specific order of columns for example, just the numbers to make the file easier to parse). Once I have that, it would be nice to have a simple tool that would take one of these tabular files as input and spit out appropriate statistics about each column (mean, mode, median, stddev, highlight outliers, etc.). If some sensible (i.e. meaningful) graphs can be generated from this data using gnuplot or some such that would be nice, too.
