Shared local cache
The Shared local cache will boost performance in virtualized environments by eliminating duplicate scanning in the network. This ensures that each file will be scanned only once and stored in the shared cache. Turn on the Caching option switch to save information about scans of files and folders on your network to the local cache. If you perform a new scan, ESET Mail Security will search for scanned files in the cache. If files match, they will be excluded from scanning.
Cache server setup contains the following:
•Hostname - Name or IP address of the computer where the cache is located.
•Port - Number of the port used for communication (same as was set in Shared local cache).
•Password - Specify the Shared local cache password if required.
