Toronto Code Sprint 2009 : The Need for Speed...

Performance is the universal feature, and the latest Geoserver vs Mapserver results indicate that there are places throughout the C stack that can use improvement.


  • Run Mapserver under load and review where Proj4 takes a hit (everywhere)
  • Caching of PJ structs, Should make QGIS and Mapserver faster.
  • Possibility of a new/simple API + optimized database sitting on top of PROJ4 to replace current init files and address some performance issues as well as allowing lookup of additional information such as axis order of a given SRS (required for WMS 1.3.0 and other OGC specs)
  • bring epsgaxis axis flipping behavior into proj4 proper


  • Run the Geoserver benchmark tests under profiler and review results
  • Single-pass querying, will bring WFS speed up to par
  • Mapserver as Apache module, removes FastCGI instability and is potentially even faster, see #2565
  • Roadmap for 6.0
  • XML Mapfiles (#2872)
  • coordinating and improving msautotest (what gets added, when, etc.)
  • WMS 1.3.0 (#473)
  • resolving msOWSDispatch (#2531)
  • support for ITEM data types for WFS server (#462)
  • Discuss issue of Hiding/enabling/ignoring layers in OGC Web Services (see Trac wiki page)
  • Discuss coordinate axis order for WFS 1.1.0 (#2899)
  • OpenGL/Cairo/VtableRendering merge. Discuss some backwards compatibility changes implied by the rendering unification (notably on symbol orientation, and linestring markers)
  • Choose one of Steve's logos
  • Discuss better handling of resolution for printing maps


  • Adding the ability to read z/x/y tiles (e.g. TMS, OSM, etc.) alongside the existing WMS reader support


  • Roadmap for 1.5+
  • New on-disk format? Aligned double?
  • New GEOS coordinate sequence to bind on top of aligned PostGIS structures?
  • Profiling and review profile results

PostGIS WKT Raster

  • Discuss WKT Raster API, roadmap and funding
  • Importer/exporter (raster2pgsql.exe, PGAdmin extension, new Paul's GUI, driver for GDAL, SQL importer function)
  • Discuss WKT Raster and PostGIS web site, source integration and bug tracking.
  • Discuss GiST index.
  • Discuss Windows build.


  • Administrivia, what to do without a full-time maintainer?
  • Roadmap for 3.2?


  • Supporting inline streaming compression
  • Win64 builds
