Basic Premise

The performance shoot-out presentation at FOSS4G2009 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

  1. All parties must contribute any changes that they make to their software for this exercise, back to their community.
  2. Comparisons will be made of the latest released software version (i.e. "stable") and also development versions of the software (i.e. "open"). For example, MapServer 5.4.2 will be tested as well as MapServer SVN trunk. Similarly GeoServer 1.7.6 will be tested as well as GeoServer SVN trunk.
  3. Data formats used must be shapefiles for vectors, geotiff files for rasters, and PostgreSQL/PostGIS for database. If you wish to test other formats/backends (such as SDE or ECW) you may do so, but that is optional for all parties. See below for access to the required data.
  4. Output formats are: jpeg for imagery, gif for non-antialised vector provided we do any, and png24 for antialiased
  5. Nearest Neighbor resampling should be used for raster image display

Coordination

Coordination 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

    • Minutes:
      • jmckenna: Need confirmation from ERDAS so press release can move forward
      • msmith: can setup rhel 5 64 bit with sde 9.3.1 and oracle 11g 64 bit for SDE (need confirmation from ESRI that this setup is OK)

Hardware

Machine A (server)

  • System Type: Dell PowerEdge 2850
  • Ship Date: 10/21/2004
  • 2 X Processor, 80546K, 3.4G, 1M, Xeon Nocona, 800
  • 4 X DIMM, 2G 400M, 128X72, 8, 240, 2RX4
  • 6 X Hard Drive, 73GB, SCSI, U320, 15K
  • Service Tag: 16GRV51
  • OS: Centos 5.3 + updates

Machine B (testing box)

  • System Type: Dell PowerEdge 1750
  • Ship Date: 9/23/2003
  • 1 x Processor, 80532K, 3.06GHz, 512K 533
  • 2 x Dimm, 512, 266M, 64X72, 8K, 184, 1U
  • 2 x Hard Drive, 300Gb, SCSI, U320, 10K
  • OS: Centos 5.3 + updates

Layers

  • texas_roads_unstyled This test exercises raw data access speed. The lines are black, the background is white, there are a hundred or so lines in each output image. The output is a two-color PNG8 image.
  • texas_roads_styled This test exercises the renderer a bit more. The lines will be "pipe-styled" and different road types will have different styles.
  • texas_roads_styled_scale This test exercises the renderer a bit more. The layer should be a single table/shapefile, the styling would just draw the highways up to a certain scale, and all the roads afterwards. The stress test shall jump between zoom levels to assess the rendering is smart enough to read only the necessary data.
  • texas_roads_styled_labeled This test exercises the render and the label algorithms. Combine the above style with road labels. Labels will follow curves. TODO(Define the expected labeling look. We know that exact matches between engines will be impossible, this will be a "best efforts" test)
  • point_layer_styled This test exercises the ability of the renderer to build a map in which points are symbolized with a certain number of externally provided icons (png/svg) depending on some point attribute.
  • polygon layers Include one or two test layers to exercise polygon rendering, with solid fill or hatch patterns. For this test the type of classification matters less than the number and complexity of the polygons (number of vertices and rings) which is the aspect we should work on. e.g. render maps with a few complex polygons vs other maps with lots of small polygons.
  • single big ECW file (actual data TBD). This test exercises the ability to read a single wavelet compressed file and return it in JPEG format.
  • file system mosaic of TIFF tiles. Generated out of the ECW file by splitting it into a sizeable amount of tiles, this test checks the ability of the server to efficiently retrieve data from a large collection of images and deal the associated file handling issues (ulimit and the like). It can also serve as a comparison with ECW results.
