Hello,

Thank you again for all the work on Orthanc.

I had a query about this configuration:

```auto
/**
 * Set the size of the cache that stores the DICOM files. This
 * size is expressed in megabytes. The default value of 128MB
 * should work in most setups, except if very large multiframe
 * instances are encountered, which might for instance be the case
 * for mammography. Setting this parameter to zero will disable
 * the cache, which should only be done for testing.
 **/
"DicomCacheSize" : 128,

```

given that we have some multiframe MRI instances with several thousand frames, whether I should consider setting this to a high number? When trying to view these images the RAM usage of the server can be incredibly high (\>16GB) and I didn’t know if changing the config might help.
