Benchmarking 2010

Basic Premise

Following up on last year's exercise, the performance shoot-out presentation at FOSS4G2010 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.

September 6-9, 2010	present results at FOSS4G2010

Rules of Engagement

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

Datasets

A set of data published by the spanish National Mapping Agency will be used. This data is free for non-commercial use, so it's perfectly OK to use it in the benchmark.

Vector data will be a topographic map, composed of several shapefiles (one shapefile per theme). Raster data will be 50cm/px aerial photography.

We still do not have the definitive datasets, due to their size and the processing time needed to put them together. You can get some sample data by reading Benchmarking 2010/How to get some sample data.

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 June 23rd @ 15:00:00 UTC
  • Agenda:
    • update on proposed layer styling
    • update on available server specs

        • msmith and jmckenna to examine styling for one sheet (Barcelona, sheet# 420)
      • each base and best run will test data in raw projection (ETRS89 + UTM28/29/30/31) and then reprojected on-the-fly to the Google Mercator projection
      • threads (number of concurrent requests) will be: 1-2-4-8-16-32-64
      • US Army Corps is proposing to provide 4 desktop machines. 2 identical for testing ( win/lin ) and 1 for jmeter and 1 for databases
        • msmith will find out availability of 2-cpu machines this week
