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.
