Benchmarking 2011

Basic Premise

Following up on last year's exercise, the performance shoot-out presentation at FOSS4G2011 will test how long each Web mapping server takes to generate a map image, from a common set of spatial data, on a common platform. The data will be served by each Web mapping server through the WMS standard, which will serve exactly the same set of LAYERS. A JMeter load will be run on the testing box to measure various aspects of those layers.

Rules of Engagement (unofficial, copied from 2010)

1. All parties must contribute any changes that they make to their software for this exercise, back to their community. Note that the changes don't have to be contributed before the conference, just in a reasonable period of time.
2. Comparisons will be made of the best available version of the software, be it a formal release or a development version.
3. Two tests will be run: one 'baseline' test with the data in its raw format (with spatial indexes), and another 'best effort' test where 'the sky is the limit' for what changes you want to make to the data (change format, generalize, etc)
4. Teams must document all steps they did to manipulate the data/server for both the 'baseline' and 'best effort' tests. If a team does not document the steps on this wiki then that team's test results will not be used.
5. Data formats to be used will be shapefiles for vectors, and uncompressed geotiffs for rasters.
6. WMS output formats to be used will be png8 and png24 where possible

Documenting Server Details and Differences

It is the responsibility of each team to document their setup with regard to data.

Please keep your notes either on a wiki subpage or in svn (or both).

Generally teams keep notes on setup on the wiki while they put stylesheets and scripts in svn.

A good organization for wiki pages is to create a subpage like: http://wiki.osgeo.org/wiki/Benchmarking_2011/Mapnik_notes

And create a directory in svn named {servername}/{year} like: http://svn.osgeo.org/osgeo/foss4g/benchmarking/mapnik/2011

SVN

The project files (minus data) are stored in Subversion (http://svn.osgeo.org/osgeo/foss4g/benchmarking/).

Communication

Coordination/communication is primarily via the Benchmarking mailing list: http://lists.osgeo.org/mailman/listinfo/benchmarking

Weekly meetings will occur through IRC chat in the #foss4g channel on irc.freenode.net

Next IRC meeting

• Wed January 12th, 2011 @ 15:00:00 UTC
