Table 2. Elements Loaded to a Network Station (MB)
The kernel or configuration data is downloaded when the Network Station is
powered-on. Unless configured otherwise, all other options are downloaded
when they are selected.
When an application (for example, 5250 emulation) is closed or the user logs
out, that application is downloaded again when it is next selected because it
is not kept in memory across log-outs. The kernel or configuration data is kept
in the Network Station across log-outs.
The download data for the Java Virtual Machine varies, depending on the
application. Only the required classes are downloaded.
In Release 3, some of the information that is sent to the Network Station is
compressed. The Network Station decompresses it after it is received. This
compression means fewer bits are shipped from the AS/400 system to the
Network Station, which results in better LAN utilization. More data and
function is shipped to the Network Station in Release 3 than in previous
releases. However, the compression results in boot performance that is about
equal to previous releases.
