.SH NAME
|
|
relbench \- John the Ripper benchmark output comparison tool
|
|
|

.SH SYNOPSIS
|

.B relbench <BENCHMARK-FILE-1> <BENCHMARK-FILE-2>

.SH DESCRIPTION
|
|
.B relbench
|
|
is a Perl script to compare two "john --test" benchmark runs, such as for
|
|
different machines, "make" targets, C compilers, optimization options, or/and
|
|
versions of John the Ripper.
|
|
|
|
To use it, redirect the output of each "john --test" run to a file, then run the
|
|
script on the two files.
|
|
|
|
Most values output by the script indicate relative performance seen on the
|
|
second benchmark run as compared to the first one, with the value of 1.0
|
|
indicating no change, values higher than 1.0 indicating speedup, and values
|
|
lower than 1.0 indicating slowdown. Specifically, the script outputs the
|
|
minimum, maximum, median, and geometric mean for the speedup (or slowdown) seen
|
|
across the many individual benchmarks that "john --test" performs.
|
|
|
|
It also outputs the median absolute deviation (relative to the median) and
|
|
geometric standard deviation (relative to the geometric mean). Of these two, a
|
|
median absolute deviation of 0.0 would indicate that no deviation from the
|
|
median is prevalent, whereas a geometric standard deviation of 1.0 would
|
|
indicate that all benchmarks were sped up or slowed down by the exact same
|
|
ratio or their speed remained unchanged.
|
|
|
|
In practice, these values will tend to deviate from 0.0 and 1.0, respectively.
