Hhhhmmm. Personally, I think you're doing it wrong.

The drawing to be printed has a resolution larger of the screen (Screen

I think tha the bottleneck could be found in:
We're using GDAL and GEOS in MapWindow GIS and we use the GEOS version of
IsValid(). I think it is the same GDAL is using.
The latest version of GEOS has a IsValidReason, telling you what was wrong.
I hope it helps,
Thanks,

Hi List,
i am working with python ogr api and i check features which the
applications gets from esri shapefiles to match several criterias.
if not xOgrGeometry.IsValid():
sMsg = "IsValid check failed! We have an invalid feature

I'm on a Mac, so I normally use Shark for profiling. It's included
with Apple's developer tools.
I would definitely try running outside of a virtual machine
environment. That might be your problem, but you won't know until you
try.

I'm working on a VirtualMachine running on an usb hdd and my customer use
iMac laptop so I can't change disk.
The primary dataset is composed by a lot of jpeg download from internet and
then cached to disk.
I think the performance slowdown is caused after the creation of the
virtual dataset

This is my (ongoing) Google Summer of Code project, except I'm using
OpenCL. :D
What resampling algorithm are you using?

I use GDAL in my traffic optimization CAD program.
It is a Win32 application written in DELPHI that uses GDAL "C" API - the
binding was autogenerated by my SWIG module for object pascal.
I use GDAL to download tiles (jpeg) from OpenstreetMap and to compose a
bitmap of the area that is being viewed
In October 2008 at the European, Middle East and Africa (EMEA) User Conference,
Jack Dangermond announced that the FGB format would be published, 'as was the
shapefile', at the 9.4 release, following the completion of developments to the
structure. We were then told to expect 9.4 in summer 2009
