The Default SEGMENT SIZE parameter affects the disk I/O performance of the /var/ psf/segments file system. This parameter determines the maximum size of any temporary file created
by the Input Manager component that is stored in /var/ psf/segments. This setting determines the number of temporary files that Input Manager requires
for all print jobs submitted to InfoPrint Manager: the smaller the setting, the more
files required to process the AFP input data.This parameter can be set by using IPMMI: InfoPrint Manager→Options→Customize the Input ManagerFor Basic Server configurations, the default setting of 5000 KB per segment can be
raised to reduce the disk I/O usage
associated with reading and writing data to the /var/psf/segments file system.
For Advanced Server configurations, the default setting of 1000 KB per segment can
be raised to reduce the disk I/O usage associated with reading and writing data to
the /var/psf/segments file system; however, the default setting usually works well with most AFP production
applications.
