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.

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 (you can use webchat to connect in browser)

Next IRC Meeting

• Wed August 3rd, 2011 @ 14:00:00 UTC
  • Provisional Agenda:
    • Status of OSM vector styling from all teams
    • Discuss rasters to be used
    • Discuss testing methodology

Timeline

January 1st, 2011	begin contacting all mapping servers
March 1st, 2011	commitment due by all interested mapping servers
March 2nd, 2011	exercise begins (and weekly meetings)
June 1st, 2011	final testing begins (no more changes to data/styles/hardware, but changes to software is allowed)
September 1st, 2011	no further testing
September 2nd, 2011	final results due from all teams
September 12-16, 2011	present results at FOSS4G2011

Rules of Engagement (DRAFT)

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. One test will be run: a 'baseline' test with the data in any format desired, but teams cannot generalize or change the data's resolution from its raw values.
4. Teams must document all steps they did to manipulate the data/server (such as spatial indexes created etc.). If a team does not document the steps on this wiki then that team's test results will not be used.
5. WMS output formats to be used will be png8 and png24 where possible

Documenting Server Setup

It is the responsibility of each team to document their setup with regard to configuration details, setup notes, and differences between other servers in how data might be accessed/indexed.

Notes for each server:

• Mapnik
• Cadcorp
• MapServer

Stylesheets and scripts in svn using a directory named wms/{year}/{servername}:

• Mapnik
• Cadcorp
• MapServer

Testing Tool

JMeter is used since it can read a list of bbox's via CSV, and the machine that applies load has been updated with Jmeter 2.5 (the latest stable release at the time of the benchmark): http://www.reverse.net/pub/apache//jakarta/jmeter/binaries/jakarta-jmeter-2.5.zip

Jmeter can be run from the command line like:

    /home/jmeterusr/jakarta-jmeter-2.5/bin/jmeter

Server Ports

Each server has access to a range of ports for testing:

Mapserver - 8080 - 8089

Mapnik - 8090 - 8099

Datasets

OSM Vectors

• Benchmarking_2011/DB_Schema
• Benchmarking_2011/Imposm

CSV Files created with

./run_wms_request.sh -count 2200 -region -109 37 -102 41 -minsize 64 64 -maxsize 1024 768 -minres "2.5e-06" -maxres 0.000755 -srs 4326 -srs2 3857 -filter_within colorado.shp

Sample styling:

• mapserv6
  • MapServer Linux (with OpenLayers)
  • MapServer Win64 (with OpenLayers)

• mapnik

DEM Hillshading

Sample styling:

• MapServer 6 Hillshade

DEM Hillshading + OSM Vectors

• MapServer 6 Hillshade + OSM Vectors - Linux Win64

OSM Vector Style changes:

 LandN layers turned off (they provide background color)
 LanduseN layers set to 70% opacity

SVN

The project files (minus data) are stored in Subversion (http://svn.osgeo.org/osgeo/foss4g/benchmarking/wms/2011/).

Data are only stored on the server at '/benchmarking/wms/2011/data/'
