| 87 | | This option controls the default GDAL raster block cache size. If its value is small (less than 10000 in 1.7 and earlier, 100000 in 1.8 and later), it is assumed to be measured in megabytes, otherwise in bytes. Note that this value is only consulted the first time the cache size is requested overriding the initial default (40MB in GDAL 1.7, but often changing for each release). To change this value programmatically during operation of the pgoram it is better to use GDALSetCacheMax(int nNewSize) (always in bytes). The maximum cache size that can be specified is 2 GB, so when specifying in megabytes, don't try setting values bigger than 2147. |

Before GDAL 1.8.0, the maximum cache size that can be specified is 2 GB, so when specifying in megabytes, don't try setting values bigger than 2047. Since GDAL 1.8.0, on 64bit platforms, it is possible to specify a 64bit value through GDAL_CACHEMAX or with GDALSetCacheMax64(GIntBig nNewSize). |
