Hi, This is a call for discussion for "RFC38 - OGR Faster Open" :
http://trac.osgeo.org/gdal/wiki/rfc38_ogr_faster_open Summary --------------- It is proposed that the OGR datasource opening mechanism relies on the GDALOpenInfo class, already used by GDAL drivers, to speed-up datasource opening. The speed-up is due to the fact that the file passed to OGROpen() will be opened and stat'ed only once, whereas currently, it is opened and closed as many times as there are OGR drivers. This should be particularly beneficial for network filesystems, or when trying to open a file that is not a OGR datasource at all. E.g., trying to open a file that is not a OGR datasource currently requires 45 file opening or stat operations : $ strace ogrinfo -ro NEWS 2>&1 | grep NEWS | wc -l 45 It is expected that if/once all drivers are migrated, it will decrease to 2 operations only.
