WMS Benchmarking presentation and results, from the FOSS4G 2011 event in Denver. 6 different development teams participated in this exercise, to display common data through the WMS standard the fastest. http://2011.foss4g.org/sessions/web-mapping-performance-shootout

6. FOSS4G 2008: OpenGeo run - published the second comparison with some review from the MapServer developers. Focus on simple thematic mapping, raster data access, WFS and tile caching (Justin Deoliveira & Andrea Aime)

9. Dedicated servers

14. Same data backends

16. Data used cannot be modified for display, other than indexing

21. 16bit Band Interleved Line (BIL)

25. Processor: Intel® Xeon® E5630 2.53Ghz, 12M Cache,Turbo, HT, 1066MHz Max Mem

26. 8GB Memory (4x2GB)

27. 2TB 7.2K RPM SATA

29. 250Gb Hard Drive 7200 rpm, 4Gb Ram

33. Each test uses a random set of requests stored in a CSV file: no two requests in the same run are equal, but all servers perform the same workload

43. They will resume the tests if at all possible, and publish their results in due course

44. So watch this space

50. No shoot-out specific improvements this year, although didn't want to drop

51. Borrowed SLD 1.1 styles from Constellation team (thanks!)

52. Hopefully GeoServer keeps doing well

57. Encoding : ability to pass options for zlib/png perf

58. Line drawing : option for faster rasterization

59. Clipping : first attempt at polyline clipping

63. Might be the reason for overhead with small tiles

64. Improvements of rule-based renderer

65. New raster provider with reprojection support performed well

66. Data preparation needed, because QGIS requires a unique primary key

70. Patch to MapServer to not apply run-time substitutions (cgi)
