Description
This setting configures the maximum file size (in MB) up to which scan results should be cached. The default setting is 40MB. Files smaller than this threshold are copied completely to the Offload Scan Server and scanned. If the file is found to be clean, its scan result is cached based on its SHA 1 checksum for faster future access. Files larger than this size threshold are transferred in chunks that are requested by the Offload Scan Server and scanned and setting that threshold higher could impact the performance of the scan processes.
