Bruce,
You need the trunk of both postgis and geos to test the new
performance goodies..

Thanks Paul
I am not sure this is the place for these comments but...
I upgraded MinGW to version 5.1.3 and that fixed the crash on
Geos-3.0.0 but
I am getting compile errors on the SVN snapshot given in the link
below.
Can I test the performance upgrades using the 3.0.0 version or do I
need to
get the SVN version working?

I can't
seem to get a complete SVN snapshot when using the directions on
http://geos.refractions.net (configure is missing).
The link for geos-svn.tar.bz2
(http://geos.refractions.net/geos-svn.tar.bz2
)
gives me a 404 error.
Could you check on the hourly snapshot link?
Thanks

I had no trouble compiling GEOS SVN on MinGW.

Ok let me try this differently :)
Has anyone had any luck compiling GOES 3.0 or GEOS SVN under MingW?
It is
causing major crashes for me. If not then I will file a bug.
Thanks

I'd love to see some people here with large data volumes who
do
contains/intersects/within tests do some testing of the new
postgis/
geos prepared geometry code...
To test the new functions
- install the svn snapshot of GEOS
- install the svn snapshot of PostGIS
- use the ST_ContainsPrepared(g1,g2) predicate for the
testing
We've seen performance improvements of between 5 and 100
times
faster. The bigger and more complicated your test
geometries are,
the faster it should be.
Thanks,
P.
