fast_map_intersection
Uses parallel programming & small tricks to produce large map intersections up to 20-30x faster.
foss4g-nor-web
Web page for FOSS4G-NOR - the Norwegian edition of FOSS4G
gbb_gdal_calc
This is an alternative version of gdal_calc that allows better handling of nodata and 15-30% faster runtimes. Minimal changes to source code. It has been submitted for inclusion in the trunk GDAL distribution via trac, but it may take a long time to show up. You can use it from here in the meantime if you like.
numpy
Numpy main repository
numpy-fast-any-all
30x faster than using numpy.any/all (numpy 1.7), syntactically sweeter than numpy.logical_or/logical_and, trivial implementation, no need for idiomatic approaches to performance.
numpy-simple-select
This is a drop-in replacement for the 'select' function in numpy. It has been reimplemented to fix long-standing bugs, improve speed substantially in all use cases, and improve internal documentation. It now supports broadcasting. It also performs some extra validation of input.
par_psql
Parallel 'psql'. Run parallel queries inline in PostgreSQL’s psql tool. Useful for ‘slightly big data’, GIS.
ppppt
Parallel pl/pgsql performance tests
rbuild
rbuild
ruleparser
Quickly and easily transform geometry datasets using a set of rules stored in a spreadsheet and raster calculations. It is designed to work with 'rbuild'.
