The main InfoPrint Manager file systems are:
I/O performance is usually the limiting factor for an InfoPrint Manager production server. Therefore, spreading the InfoPrint Manager file systems across three or more drives is likely to boost performance for an InfoPrint Manager production server. Even more of a performance gain can be accomplished by putting
/var/pd on one drive,
/var/psf on another drive, and
/var/psf/segments across two more drives, striping the two
/var/psf/segments drives for better I/O performance. The first file system that should be spread across
two or more striped drives is
/var/psf/segments. You could also spread
/var/pd across two or more striped drives.
One of the settings that can be made when creating file systems is the fragment size. Changing the fragment size allows for better space utilization. For better performance, it is best to set the fragment size at its highest value of 4096 bytes even if this might cause wasted disk space. With a smaller fragment size, there might be an increase in disk I/O operations.
