I suspect those requests come from sequential reading of features. /vsicurl/ reads by chunks of 16 KB, and when it detects a sequential reading pattern it multiplies the chunk size by 2 until a limit of 1.6 MB. The 3 ranges you mention are respectively 16, 32 and 64 KB and show that x2 pattern. There is probably not much more that can be done because the driver cannot know how many features are going to be read in advance. Or that would imply a more aggressive exponential strategy in /vsicurl/, but that could have undesirable effects in other scenarios. -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
