       git-annex-benchmark - benchmark git-annex commands

       git annex benchmark [criterionopts] -- commmand [; command]

       When git-annex is built with benchmarking support, this command can be
       used to benchmark any other git-annex command. For example "git annex
       benchmark -- get ."  will benchmark "git annex get".

       The command being benchmarked is run in the current git-annex repository.
       It does not run just once; the benchmarking process will run it several
       times to get a statistically meaningful result.

       When benchmarking an action like "git annex get", the first run will
       often do much more than subseqent runs. To make the benchmark repeat an
       action like getting a file each time, additional command can be listed,
       separated by ';'. (Note that ';' needs to be escaped from the shell.)
       The combined script will be run repeatedly by the benchmark. An example
       of using this:

        git annex benchmark -- get . ';' drop .

       Note that git-annex benchmark does not fork new git-annex processes when
       benchmarking; it calls the command to benchmark internally, and so avoids
       git-annex's startup overhead. (So don't try to use it to optimise git-
       annex startup.)

       Before the "--" any of the criterion library's command-line options can
       be used.

       Any options that git-annex usually accepts can be included after the
       command to benchmark.

       The output of the commands being benchmarked goes to standard output and
       standard error as usual. It's often a good idea to sink it to /dev/null
       to avoid the display of the output skewing the benchmark results. Of
       course --quiet can also be used to avoid most git-annex output, as long
       as you don't want to benchmark the generation of that output.

       The benchmark report is output to standard output by default, although
       criterion options can be used to redirect it to a file.
