    104104Starting with GDAL 1.10, when using the VSI interface files can be cached in RAM by setting the configuration option VSI_CACHE to TRUE. The cache size defaults to 25 MB, but can be modified by setting the configuration option VSI_CACHE_SIZE (in bytes).

     106When enabled, this cache is used for most I/O in GDAL, including local files. Be wary of large values for VSI_CACHE_SIZE when opening VRT datasources containing many source rasters, as this is a per-file cache.
