Cache Size
The cache size parameter specifies the number of kilobytes of iSeries™, eServer™ i5, or System i5™ data that is buffered in the read-ahead cache of the client. The default is 256 KB; the maximum is 4 MB. A value of zero requests that no cache be used. iSeries™, eServer™ i5, or System i5™ data can be retrieved in amounts that are first cached locally on the client. The client retrieves the data from the cache to populate the local device. This read-ahead caching reduces the number of times the client has to access the iSeries™, eServer™ i5, or System i5™ to retrieve the data.
