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.

Rules of Engagement

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.
Comparisons will be made of the best available version of the software, be it a formal release or a development version.
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)
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.
Data formats to be used will be shapefiles for vectors, and uncompressed geotiffs for rasters.
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.

Server Details and Differences

It is the responsibility of each team to document their setup with regard to data. One particular thing that will differ is each team's use of spatial indexes on shapefiles.

Previous IRC meeting

Wed July 14th @ 15:00:00 UTC
- Agenda:
  - update on data processing for all of Spain
  - update on server setup
  - data styling discussions
    - scales to use for layers
    - missing full road network
    - layer to use for labels along lines
- Summary: (log)
  - Attendance:
    - Jeff McKenna (jmckenna)
    - Andrea Aime (aaime)
    - Iván Sánchez (IvanSanchez)
    - Michael Smith (msmith_)
    - Dimitri Monie (dmonie)
    - Dane Springmeyer (springmeyer)
  - Discussion:
    - data:
      - full dataset of Spain, vector and raster, has been processed by IvanSanchez, and he is checking it and will create a torrent for transfer, by the end of the week
      - because of shapefile size limit some layers may have to be split (contour-1.shp, contour-2.shp)
    - servers:
      - msmith has received both server machines
      - T1 router is being installed, it will be a dedicated line for this project
      - he is adding 2 TB drives to each
    - layer styling:
      - we notice that the Spain dataset we are using (BCN25) does not include street files (zoomed in road network)
      - we agreed to use contours for curved label tests instead
      - jmckenna will test the layer scales provided by Marco (QGIS mapserver)
      - aaime pointed out problem with the posted SLDs, in terms of the label property (jmckenna to look into it)
      - aaime pointed out that we should make sure that all servers compute the scales the same way
        OGC recommends 90 DPI (GeoServer, Mapnik use the recommended 90...MapServer defaults to 72, but should be configurable)
        
        all teams should look into how their engine handles this and report to group
    - other:
      - IvanSanchez reported that a Spanish custom-made WMS server may join the exercise (they access raster files only)
      - dmonie pointed out that Erdas has been quiet lately because one of the team leaders is on holiday
