Hello,
Qgis 1.7 compiled with GDAL / OGR (1.7.0 and superior) is very slow to
load a big ogr layer (250Mb). The same file on Qgis 1.6 compiled with
GDAL/OGR (1.5.4) opens in a few seconds.
I suspect the version of GDAL / OGR, what do you think ?
I have observed this from the point of view of two different graphical
tools displaying vector data and using the same GDAL binary. QGIS is
much slower than a simple renderer, I suspect that QGIS spends more time
because of its complex visualization possibilities (which assumably have
become more complex since version 1.7).
Cheers,
Ari
Thanks
