<h1><a class="toc-backref" href="#id1">Introduction</a></h1>
<p>GraphicsMagick 1.3.8 has been benchmarked against the most recent
ImageMagick release available at time of release. ImageMagick has been
significantly updated to use OpenMP as has GraphicsMagick
1.3.8. Several disparate types of systems were used in our
testing. While last time around, ImageMagick performance had taken a
terrific nose-dive, in this series of tests ImageMagick is much more
competitive. ImageMagick has clearly benefited from this benchmark
being available since November, 2008.</p>
</div>
<div class="section" id="executive-summary">
<h1><a class="toc-backref" href="#id2">Executive Summary</a></h1>
<p>GraphicsMagick is usually considerably faster at executing image
processing operations from the command line than ImageMagick 6.5.8-10
is. One ImageMagick algorithm runs as much as 770 times slower.
GraphicsMagick clearly runs much more efficiently under Microsoft
Windows.</p>
</div>
<div class="section" id="strategy">
<h1><a class="toc-backref" href="#id3">Strategy</a></h1>
<p>Since the 1.2.X benchmark cycle, we used a completely different
benchmark approach. Instead of testing single-shot performance with
large uncompressed files, we focused on the ability to process many
medium sized HD-resolution (1920x1080 pixels) images. In order to
prevent disk I/O from being a factor, we used a small input image and
tiled it to create a larger input image via the "tile:" coder. The
processed image is sent to the "null:" coder so that file writes to a
slow disk are also not a factor. Static executables are used and
executed via full paths in order to minimize variability from the
execution environment. In order to obtain accurate and useful timing,
we used the bash shell to execute the command 40 times and see how
long it took. This is a very simple benchmark approach which is quite
representative of the performance that the typical user observes.</p>
<p>This new benchmark reveals the following performance criteria:</p>
<blockquote>
<ul class="simple">
<li>Basic execution overhead of the software.</li>
<li>Image processing algorithmic efficiency.</li>
<li>Efficacy of OpenMP enhancements.</li>
</ul>
</blockquote>
<p>The software involved in the testing identified itself as:</p>

</div>
<div class="section" id="the-benchmark">
<h1><a class="toc-backref" href="#id4">The Benchmark</a></h1>
<p>The benchmark is quite simple. It reads a list of commands to execute
from a file named "commands.txt" and times how long it takes to
execute each command 40 times using GraphicsMagick and ImageMagick.</p>
<p>Here is the simple benchmark script:</p>

<div class="section" id="test-results">
<h1><a class="toc-backref" href="#id5">Test Results</a></h1>
<p>The test results are expressed as the image processing operation
performed, the amount of wall-clock time it took for GraphicsMagick to
execute it fourty times, the amount of wall-clock time it took for
ImageMagick to execute it fourty times, and the ImageMagick time
divided by the GraphicsMagick time. In order to understand the "IM/GM
ratio" column, a value of 0.50 indicates that GM is half as fast as
IM, a value of 1.00 indicates that GM and IM are the same speed, and a
value of 4.00 indicates that GM is four times as fast as IM.</p>

<h2><a class="toc-backref" href="#id13">Intel Pentium IV / Cygwin</a></h2>
<p>This system is a 2000 vintage 2.0GHz Pentium IV system with Windows XP
SP3 and Cygwin 1.5.25. This system has only one CPU core and the
compiler (gcc version 3.4.4 (cygming special, gdc 0.12, using dmd
0.125) does not support OpenMP so this is a single-threaded
configuration. It can be seen that ImageMagick takes much longer to
generate its tiled input image and to even get started (first -noop
entry). GraphicsMagick is faster for all algorithms:</p>
