* ``GDAL_CACHEMAX``: Gdal has an internal cache mechanism to avoid reading or decoding again image chunks. This environnement variable controls how much memory Gdal can use for caching. By default, Gdal can use up to 5 percents of available RAM on system, which may be a lot. Moreover, caching is only needed if the processing chain is likely to request the same chunk several times, which is not likely to happen for a standard pixel based OTB pipeline. Setting a lower value allows to allocate more memory to OTB itself (using applications ``-ram`` parameter or ``OTB_MAX_RAM_HINT`` environment variable). If value is small (less than 100 000, it is assumed to be in megabytes, otherwise, it is assumed to be in bytes.
* ``GDAL_NUM_THREADS``: Gdal can take advantage of multi-threading to decode some formats. This variable controls the number of threads Gdal is allowed to use.
* ``OPJ_NUM_HTREADS``: OpenJpeg can take advantage of mutli-threading when decoding images. This variable controls the number of threads OpenJpeg is allowed to use.
* ``OPJ_NUM_THREADS``: OpenJpeg can take advantage of mutli-threading when decoding images. This variable controls the number of threads OpenJpeg is allowed to use.
* ``ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS``: This variable allows to control the number of threads used by ITK for processing.
