20.1.4 Form Cache
What is the form cache? What options can I adjust with respect to the form cache?
The form cache is an amount of RAM set aside to hold images that the document references during execution.
The cache improves performance by providing faster access to images that the document uses more than
once.
The size of the cache and the order in which the document executes the images determine the contents of the
cache at any given point in time. As the cache fills, the printer may have to remove images to make room for
the most recent image. When it must remove an image, the printer removes the least recently referenced
one.
In PlanetPress Design, you can set both the size of the printer form cache and the maximum size of an
individual cache item. You can set these options for all documents that execute on the printer.
When you set the cache options, you should know that the images in the cache have already undergone part
of the rasterization process and that this may have increased their size, sometimes quite substantially. Since
this difference in size depends on the individual image the best approach for determining appropriate values
for the cache options is empirical: if document execution is slow, adjust the value and see if performance
improves.
